All answers are provided I've designed this lesson to build up students knowledge of error intervals. It includes questions on nearest whole, ten and hundred; nearest five, fifty and five hundred; decimal places and significant figures. It begins with a stopwatch starter where students need to to answer 4 questions based around rounding. This leads into a definition about error intervals and why we use the inequality symbols. A nice class discussion is formed around why 3.4999... would be written as 3.5 with a less than symbol for the upper bound. Nearest whole, ten and hundred - 3 examples - 5 Miniature whiteboard multiple choice questions - 15 your turn questions Decimal places and significant figures - 3 examples - 5 miniature whiteboard questions - 12 your turn questions Nearest five, fifty and five hundred; - 3 Examples - 5 miniature whiteboard questions - 15 your turn questions The resource then in includes a differentiated focused activity which progressively gets harder. This gives students a chance to master and enhance their skills. It includes 4 separate sections: skills 1, 2 and 3 and stretch 1. These are all displayed on the same slide for ease of use, however could be printed as a worksheet. Then to finish there is an application on how this could be seen in an exam situation with 2 exam style questions including answers. I hope you find this resource as useful as my students have. Any of the the slides could be printed as worksheets if you feel that would be easier for your class. Miss B

Updated 22nd September 2017 (All answers are provided) I've designed this resource to allow students to start to understand substitution from the basics upwards. It begins with a stopwatch starter asking students to simplify basic algebraic expressions. This leads to a restaurant menu activity and a class discussion about how they intrinsically know how to substitute to find the total cost. I've found it's important to look at the language of mathematics to help students understanding. I find a perfect activity for this topic is connections, here students have to make links related to substitution and the words on the page, I've provided an example and then some possible answers for this. This means moving forward I can use mathematical language, such as variable, and be sure the students understand it's meaning. Afterwards there is a quick true or false activity with the answers, you could do this as a mini whiteboard activity, class discussion, group task or silent focus. I personally use this with whiteboards and hammer out the misconceptions. It is a good tool in getting the students to practise providing explanations and reasons verbally for their answers. I've then modelled 4 different examples of varying ability and these appear step by step and include examples with negative numbers. There is then a catchphrase quiz activity which I find useful to hammer out any misconceptions the students may have. (The answers or on the next slide for this, some teachers may find it useful to jot these down or print that slide before completing the interactive activity). The catchphrase is bad hair day. The resource then in includes a differentiated focused activity which progressively gets harder. This gives students a chance to master and enhance their skills. It includes 4 separate sections a skill 1 & 2 and a stretch 1 & 2. These are all displayed on the same slide for ease of use. (Answers are provided) Then to finish there is an application on how this could be seen in an exam situation including answers. I hope you find this resource as useful as my students have. Miss B

All answers are provided I've designed this lesson to build up students knowledge of calculating with bounds to find the upper and lower bounds. It begins with a stopwatch starter where students need to to answer 4 questions based around rounding. A class discussion over how limits of accuracy could affect a consumer buying goods by weight. This leads to a recap on error intervals and a class discussion around why 3.4999... would be written as 3.5 with a less than symbol for the upper bound. Error Intervals - 2 examples - 6 Mini Whiteboard Questions - Bronze, Silver & Gold Your Turn Section Multiplying and Adding with Bounds - 2 Examples - Bronze, Silver & Gold Your Turn Section Dividing and Subtracting with Bounds - 2 Examples - Bronze, Silver & Gold Your Turn Section The resource then in includes a differentiated focused activity which progressively gets harder. This gives students a chance to master and enhance their skills. It includes 4 separate sections: skills 1, 2 and 3 and stretch 1.

Updated 13th September (All answers are provided) I’ve designed this Lesson to allow students to explore multiplying and dividing negative numbers building up from the basic pictorial through the use of counters and coming to identifying quicker methods/ rules. This then leads to 6 basic examples of mutliplication questions such as -2 x 3 and -2 x -3. The examples are broken into to groups of 2 and are each followed by four questions for students to try. Answers are given with full pictorial and written solutions. This leads to a class discussion on quicker methods now that they why is understood. Student have the pictorial to fall back on if they get stuck. There is then a similar structure for division of negative numbers. A true or false activity to be used as a discussion point over the generalisation of how rules work. There is a Bingo quiz activity which can be used to help stop misconceptions before the main differentiated activity. The resource then in includes a differentiated focused activity which progressively gets harder. This gives students a chance to master and enhance their skills. It includes 5 separate sections a skill 1, 2 & 3 and a stretch 1 & 2. These are all displayed on the same slide for ease of use. Then to finish there is an application on how this could be seen in an exam situation including answers. I hope you find this resource as useful as my students have. Miss B Bonus Materials There is an extra challenge slide of an multiplication grid of negative numbers. There is also a mixed challenge activity to be used with students once they have learnt how to add, subtract, multiply and divide negative numbers. I have attached printable versions of the grid I use throughout the slides. I often laminate them for the students to do the examples with me in lessons)

All answers are provided I've designed this lesson to build up students knowledge of rounding to decimal places . It begins with a stopwatch starter where students need to to answer 4 questions based around rounding to the nearest whole, ten and hundred. This is then followed by a class discussion and definition of what rounding is and why we might round. Leading into the main part of the lesson. Rounding to 1 decimal place - 3 examples - Code breaker activity where students have to round the numbers and equate these to a letter in the key. It makes a maths joke. Rounding to 2 decimal places - 3 examples - Multiple choice mini whiteboard quiz (6 questions) This then leads into an exercise including 15 questions which get progressively harder. - 5 x 1 decimal place - 5 x 2 decimal place - 5 x 3 decimal place The resource then in includes a differentiated focused activity which progressively gets harder. This gives students a chance to master and enhance their skills. It includes 3 separate sections a skill 1& 2 and a stretch 1. These are all displayed on the same slide for ease of use.

(All answers are provided) I've designed this lesson to build up students knowledge of expanding single brackets. It begins with a stopwatch starter where students need to to answer three simplifying algebraic expression questions. This then leads to discussion over methods you could use to answer numerical questions such as 3(5-2). I'm very much aware that there are 3 different common approaches to teaching expanding brackets. I've included 4 examples for each of the following methods (12 different examples). I know the method I teach sometimes varies on the class I am teaching. 1) Algebra tiles - Explanation slides of how to multiply with algebra tiles, 4 progressively harder expanding bracket examples with algebra tiles and 4 mini whiteboard questions for the students to do themselves with algebra tile solutions. 2) Grid Method - 4 progressively harder examples of expanding brackets using the grid method, 5 mini white board questions 3)Claw/Arrow method - 4 progressively harder examples of expanding brackets using claw method and the same 5 mini white board questions as the grid method. This then leads to three tick or trash questions, where the students need to select which person has answered the question correctly and discuss what the misconception of the other person was. There is then a matching quiz interactive activity where students can come to the board, selected two cards and see if they are a pair. If they are leave them turned over, if not click the cards again to turn them back over. The resource then in includes a differentiated focused activity which progressively gets harder. This gives students a chance to master and enhance their skills. It includes 5 separate sections a skill 1, 2 & 3 and a stretch. These are all displayed on the same slide for ease of use.

(All answers are provided) I've designed this lesson to build up students knowledge of rounding to significant figures. It starts with 10 quick fire questions on rounding to the nearest 10, 100, 1000 and decimal places. Then the definition of what significant figures are is given and to be discussed. This leads into a True or False activity where students need to decide how many significant figures each number has. Following this are the first 3 examples out of 6. These deal with rounding to significant figures when 0's aren't involved. These are fully animated through clicking to get to the next step. These then leads to 3 mini whiteboard questions for students to attempt themselves. Now its time for the next 3 examples. These deal with rounding to significant figures and the 0 rule. I often have a big class discussion around this concept. These examples again lead onto 5 mini whiteboard questions for students to attempt themselves. Then there is an interactive pairing activity where students need to come to the board and select two cards. If they are a matching question and answer then leave them turned over, if not turn them back over and start again. (Snap) The resource then in includes a differentiated focused activity which progressively gets harder. This gives students a chance to master and enhance their skills. It includes 4 separate sections a skill 1, 2 & 3 and a stretch. These are all displayed on the same slide for ease of use.

(All answers are provided) I've designed this lesson to build up students knowledge of expanding double brackets. It begins with a stopwatch starter where students need to to answer four simplifying and expanding algebraic expression questions. This then leads to discussion over methods you could use to answer numerical questions such as (2+3)(1+2). Then there is a product and sum activity. (3 questions where students need to find the product and sum and 3 questions where students have to work backwards from being given the product and sum) I'm very much aware that there are several different common approaches to teaching expanding brackets. I've included examples for each of the following methods. I know the method I teach sometimes varies on the class I am teaching. Feel free to swap the order and delete the examples you don't want, I felt it was important to give options though. Form x^2+bx+c 1) Algebra tiles - Explanation slides of how to multiply with algebra tiles, 3 progressively harder expanding bracket examples with algebra tiles and 5 mini whiteboard questions with both written and algebra tile solutions. (These 5 whiteboard questions can be used even if not teaching with algebra tile approach) 2) Grid Method - 3 progressively harder examples 3)FOIL/Half moon - 3 progressively harder examples 4 questions for students to try in book. Form ax^2+bx+c 1) Algebra tiles - 2 progressively harder expanding bracket examples with algebra tiles and 2 mini whiteboard questions with both written and algebra tile solutions. (These whiteboard questions can be used even if not teaching with algebra tile approach) 2) Grid Method - 2 progressively harder examples 3)FOIL/Half moon - 2 progressively harder examples 4 questions for students to try in book. This then leads to two tick or trash questions, where the students need to select which person has answered the question correctly and discuss what the misconception of the other person was. There is then a n interactive wheel of fortune quizzing activity where students can come to the board. Spin the wheel, click the section it lands on, answer the question and total their points. The resource then in includes a differentiated focused activity which progressively gets harder. This gives students a chance to master and enhance their skills.
