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

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.

Visual introduction to square number patterns . Useful as a visual introduction to exploring square numbers and/or as a lesson starter. A square is slowly built by adding the next odd number of squares to the first to make a bigger square (number). 3 animated slides (don't bore your students too much, just use 1 a lesson) *Slide 1 uses a growing pattern of odd numbers in an addition sentence (underneath the square) to create square numbers. *Slide 2 uses the above plus the matching multiplication sentence. *Slide 3 uses the visual and only the multiplication sentence. I like to show slide 1 with just the addition sentence first off and impress my students with my quick fire maths skills ;-) "1+3+5+7+11+13+15+17+19+21+23 = 135". The following day I'll teach them the trick of multiplication. A few of my higher ability will be able to answer the addition sentences on their own at the end of a lesson. You'll need a bit of patience as the squares reveal themselves. Hope students around the world enjoy it (?) and that it makes multiplication that little more understandable. Please rate and comment politely, all my resources are shared freely.

Find x more than using the number line, then write the addition sentences. Find x less than using the number line, then write the subtraction sentences. Start number given. Students then fill in + or - and the other numbers to make the number sentences. Please rate and comment.

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)

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.

An introduction of the ‘think multiplication strategy’ to help with division. An animated, interactive PowerPoint presentation with arrays of dots to help students visualize related multiplication and division facts. A partially covered array showing only the number of rows in an array, but not the number of dots in each row is shown, along with a matching fact statement (e.g. “Altogether there are 40 dots”) Students are encouraged to give the multiplication sentence AND related division sentence using the information shown (total number of dots & number of rows/groups) that helps work out the array proportions. e.g. 5 x ? = 40 and 40 ÷ 5= ?. 14 example arrays. Includes 3 level differentiated division / multiplication worksheet in same style, plus colour matching facts for all tables x2-x10
