Here is a 5 day teaching unit using PowerPoint for anyone who is wanting to teach students about how to use and reason with numbers. The lessons start with a 10 minute mental warm up session. This is followed by a highly interactive, whole class teaching session. The PowerPoint lessons end with a differentiated teaching challenge for students at different attainment levels. Autumn Term Lesson 1: Week 8 Title Counting and Properties of Numbers Learning Objective:  count on in steps of any size  solve number patterns  make up our own number patterns. Lesson 2: Week 8 Title Counting and Properties of Numbers Learning Objective:  count on in steps of any size  solve number patterns  make patterns agree with rules  make alternating patterns. Lesson 3: Week 8 Title Reasoning about Numbers Learning Objective:  investigate square numbers  find ways of investigating numbers  find square numbers by using a pattern. Lesson 4: Week 8 Title Reasoning about Numbers Learning Objective:  solve word problems  recognise odd and even numbers  find and talk about general statements  develop mental strategies. Lesson 5: Week 8 Title Reasoning about Numbers Learning Objective:  add and subtract  use the words used to add and subtract  add several numbers together and find the differences by counting on.

Here are 5 great PowerPoint lessons about addition, subtraction, rounding and money to use in the classroom. The lessons are complete with 3 parts. The first part is the 10 minute mental warm up session. The central part in the whole class, interactive learning session. The final part of the lesson provides differentiated challenges for the students. Autumn Term Lesson 1: Week 9 Title Addition and Subtraction Learning Objective:  complete adding and subtracting problems  add several numbers  understand that adding but not subtracting can be done in any order. Lesson 2: Week 9 Title Subtracting from Multiples of 10 Learning Objective:  understand the words used to describe adding and subtracting  subtract a one-digit number from a multiple of 10  record the answers in different ways.  Practise subtracting from multiples of 10.  Practise subtracting from bigger multiples of 10. Lesson 3: Week 9 Title Subtraction Learning Objective:  use words to describe subtraction  subtract a one-digit number from a multiple of 10. Lesson 4: Week 9 Title Describing Money Learning Objective:  use words to compare and order numbers  recognise coins  total money  understand different monies can be the same. Lesson 5: Week 9 Title Rounding and Money Problems Learning Objective:  round amounts to the nearest 10p  approximate and order numbers on a number line  recognise coins  be able to total money together.

Three full PowerPoint Lessons about counting and properties of numbers which start with a fun mental warm up. The students then experience a fully interactive, main class leaning session. The lesson finishes with a fun differentiated learning challenge. Summer Term Lesson 1: Week 1 Title Counting and Properties of Numbers Learning Objective:  recognise odd and even numbers  understand what is special about odd and even numbers  count on and back in twos. Mental Warm Up: Counting on and back in ones. Counting on and back in tens. Main Lesson Idea: Today we are going to investigate sharing by 2. Educational Challenges  Investigate which numbers can be shared equally by 2. Look for patterns and predict results.  Investigate which numbers less than 30 can be shared equally by 2.  Investigate which numbers can be shared equally by 2. Predict results for numbers greater than 100. Lesson 2: Week 1 Title Counting and Properties of Numbers Learning Objective:  say what is happening in a number pattern  say what number is next in a number pattern  count on and back in steps of different sizes. Mental Warm Up: You each have a number card. Is your number odd or even? Main Lesson Idea: Today we are going to be counting on and back in steps of different sizes. Educational Challenges  Make up number chains using ‘add’ and ‘subtract’. Predict whether the final number will be more or less than the start number.  Make up number chains using ‘add’ and ‘subtract’. Ask a classmate to work out the end number. Lesson 3: Week 1 Title Counting and Properties of Numbers Learning Objective:  count on in twos, fives and tens  recognise multiples of 2, 5, and 10  be able to explain number patterns  recognise that some numbers can be a multiple of more than one number. Mental Warm Up: Today you will be counting on and back in twos, fives and tens. Main Lesson Idea: Today we are going to recognise multiples of 2, 5, and 10. Educational Challenges  Colour in multiples of 2, 5 and 10 on a hundred square.  Practise recognising multiples of 2, 5 and 10.
