Grid Method / Place Value PowerPoint uses arrays and smiley faces to show the mental multiplication strategy of using place value and knowledge of multiplication to work out a 2-digit number by a 1-digit number - with exchange (such as 8 x 35, 9 x 33 etc.). No text to read or get distracted by. 12 examples which build from 4 x 18 & 3 x 22 on the first two slides up to 9 x 33 & 8 x 83 on the last two slides. All slides follow the same animations: *Array and multiplication problem is shown. Confused smiley bounces in (teacher explains that if you don’t know your 83 times table you’re going to be confused) *array changes to show place value calculations. *Confused face is replaced by a happy face as he can now do the multiplication problem. 12 examples clearly help grade 3,4 or 5 students master and understand this important skill. With matching differentiate worksheets for multiplying 2-digit number by a 1-digit number.

8 Mental Strategies for Multiplication These thoughtfully made PowerPoints are carefully designed to help students grasp commonly taught multiplication strategies ( and tricks) for x0, x1, x2, x3, x4, x5, x8, and x9 times tables. Ideal for years 3 and 4, but also helpful for year 5 and 6. To multiply by 2 = double the number To multiply by 3 = double the number and add a set To multiply by 4 = double, then double again. To multiply by 5 = multiply by 10 then halve To multiply by 8 = double-double-double To multiply by 9 = use your fingers/ the digits of answer added = 9 To multiply by 0 = the answer is always 0 To multiply by 1 = the answer is always that same number. All the PowerPoints include examples to 12 and extensions to large multiplications to show that the strategy really comes in useful for doing tricky mental multiplication. Please see video for a taster. All slide animations are activated when you click the mouse, giving teacher and student thinking and explaining time. Video is sped up to get through the examples. Includes some supporting, differentiated worksheets

Compensation Strategy for Mental Subtraction. By visually illustrating the mental subtraction strategy of compensation by using moving base ten blocks and a bin my students where able to better understand how answers are adjusted by adding back or subtracting more and therefore compensating for the rounding which made the question easier. PowerPoint includes 5 examples with base ten blocks and 5 matching slides with matching sums but just the thought process and 2 additional examples without base ten blocks to help learners move from a pictorial representation to an abstract one. Download includes a double sided worksheet based around the PowerPoint teaching.

Three rimes table trick with arrays to help with the three times table multiplication strategy . This clear, step-by-step and helpful PowerPoint will help students learn that multiplication by 3 can be done by doubling and adding another set. e.g. to calculate 3 × 14: first double 14 getting 28, then add another 14, (to get 3 times 14) which is 42. 21 Examples are presented (from 3 x 2 up to 3 x 21) in order, or from a hyperlink menu. Each slide shows the sum and a confused face, Then two lines of the matching array (showing the doubling array) Then another set (another line of the array) is added Whilst the matching thought process is shown with clear sums. Finally everything apart from the x3 sum and array dissolve out, leaving just the sum, the answer and the x3 array. Each part of the thought multiplication strategy is presented when you click the mouse, giving students time to work out and explain each step. Includes 3 level differentiated mathcing sylte worksheets and skip counting x3 worksheets.

A PowerPoint which introduces the ‘Doubling-and-Halving Strategy for Multiplication’. This PowerPoint uses an array to show the multiplication strategy of doubling one factor and halving the other factor to help to work out some multiplication problems. Doubling and halving is therefore related to thinking that ‘restructures’ an array to make it more manageable to multiply (e.g. 3 × 18 = ___ can be rewritten as 6 × 9 = ___). Very visual resource which helps students see that the total number of circles in an array (the product) stays the same when an array is cut and rearranged. No text: so recommend that the teacher walks through the first couple of example slides and then students verbally explain the following examples to their peers. Order of animations: Tricky array and sum is shown. Confused smiley bounces in. (explain here that if you don’t know your 15 times table etc. this could be hard) Scissors appear and cut the array - array restructures into simpler array (double of one factor/half of the other) New corresponding sum appears - click & answer is shown Array restructures to first formation and tricky sum is shown again As the total number of circles has remained the same throughout the sequence the answer should be obvious :-) I use it alongside other strategies so that it is presented as an option for mental computation involving multiplication.

Think Addition Strategy to do Subtraction mental math 2 Presentations & 8 Worksheets - Think-addition-to-do-subtraction is a mental math strategy that introduces students to the concept that there is an inverse relationship between addition and subtraction. You think of an addition fact in the same fact family. For example, you can solve 10 - 4 = ? by thinking 4 + ? = 10 and knowing that 4 + 6 = 10. I made these two PowerPoints to help my grade 3 class (ages 8 & 9) with the think-addition strategy. Many of my students this year are slow to recall number-bond facts, and therefore this has hopefully helped them to see the inverse relationship between addition and subtraction. Could well be used in earlier grades. 1 PowerPoint of 25 sums with matching circles being added and taken away: mainly for subtraction sums between 10-20, but also has 4 slides for facts to 10. Slides can of course be hidden and order rearranged. 2nd PowerPoint of 20 larger sums with no circles: variety of examples within 100. Comes with seven subtraction think addition worksheets in PDF format of increasing difficulty, and 1 editable microsoft word worksheet.

Input-Output Tables to help relate multiplication and division. PowerPoint focuses on building a connection between multiplication and division operations using an active model to reinforce the connection between the two operations. Visual of the relationship between division and multiplication using input and output tables to show that division is sharing and multiplication is combining. The PowerPoint is designed to encourage students to combine equal groups of clipart images to make a total (multiplication), as well as share a collection to form equal groups (division). The PowerPoint uses a variety of public domain clipart images to act out a multiplication or division problems to encourage students to determine the total and reverse the action to determine the quotient and vice versa. Your students can make up little stories to help them understand each operation. x3/÷3 & x4/÷4 Facts used (28 slides). Includes differentiated worksheets for 3’s and 4’s facts

The seaside themed PowerPoint explains and shows what an array is, with fun seaside and beach illustrations, arrays using circles, clear examples, top tips for saving time e.g. counting in 2s, 5s and 10s. (Please see video for a 8 second per slide run through of the PowerPoint, actual PowerPoint is far smoother and controlled via right click to begin each animation, giving time for explanations and children to think and answer) Also included a fun, introductory array cut-match-stick worksheet (2 version: one at a lower level and one slightly harder)

Made for my grade 3 class who are just starting to formally learn their times-tables. Very visual resource using arrays with dots, hundred charts, step counting and various sum flashcards. PowerPoint activity/presentation progressing in this slide order: Counting in steps of two up to 120 from 0. Count to 24 in steps of 2 with array being built. 100 square count in steps of two with pattern being revealed (2 sec each step). 100 square count in steps of two with pattern being revealed (1 sec each step). Double the number with numbers in random order (doubling function in-out machine design). 2 times table with sum and array in order. 2 times table with sum and array turnaround in order. 2 times table with sum but no array 2 times table with sum and array out of order. Answer shown and student to give sum. Also included are the x0 and x1 timetables. Often overlooked when teaching multiplication, but essential to grasping a true understanding. First slide is ‘times zero’ times table and shows a fixed golden zero with sum twisting in and out. Emphasizing the rule that; “When you multiply a number by zero, the answer is always zero” Second slide is ‘times one’ times table and shows the multiplicand (the number being multiplied) emerging from itself and sliding over to the product (the answer) Emphasizing the rule that; “Any Number Times One is that Number / 1 x anything = itself”

Blank 0-20 numberlines (with equal lines increasing by 1s) & 0-100 numberlines (with increases by fives and tens) And one A4 page of 100 numberlines, with increases by 1s (small gray lines) and long black line showing steps of 10. Use them how you wish...start at 0, start at 300, start at 900. For students to fill in the numbers under or above the dashes.
