Division Inverse of Multiplication Speed Math
Beginner division speed math worksheets introducing/reinforcing division as being the inverse of multiplication - "Think multiplication" (to do division)
Files - 'speed division inverse of multiplication_worksheet1' & 2 present multiplication turnaround facts followed by matching inverse division facts in groups of 4.
e.g.
5 x 2 =
2 x 5 =
10 ÷ 2 =
10 ÷ 5 =
File - 'speed division inverse of multiplication_using multi to divide_missing multiplier2_4_6_8_9'
Present only one multiplication followed it's inverse division, in columns of facts for 2, 4, 6, 8, and 9 times tables:
e.g.
2s Facts
2 x ___ = 18
18 ÷ 2 =
2 x ___ = 14
14 ÷ 2 =
Other worksheet presents mixed problems with the multiplication having the missing multiplier
e.g
2 x ___ = 18
18 ÷ 2 =
Students are therefore encouraged to 'think multiplication' when doing division.
2 Digit by 1 Digit Multiplication
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.
Number Bonds to Five
5 + 0 = 5, 4 + 1 = 5 ....I'm sure you know the rest?
Inside the table draw &'add&'; the required number of circles to make a total of five. Then fill in the addition sentence below the circles. Number bonds to five. Addition.

Mental Multiplication Strategies
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
Number Line Subtraction Monkey
Number line subtraction from 20.
Each question has an accompanying number line with a red start number and dot.
Lots of monkey clip art. (I use it with an excellent 'monkey subtraction to 10' Power Point >>> cut and paste:>> http://www.tes.co.uk/teaching-resource/Monkey-Subtraction-to-10-6309981/
Worksheet 2 has an additional page with lots of questions and only a few number lines.
Please comment and rate.
Blank Numberlines
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.
I will print onto card and laminate, or stick on top of mini whiteboards and call out numbers for students to locate the number on the numberlines.
Number Line Addition
First number line addition (totals up to 20) jump making worksheet WITH FROGS!
Easy to change the questions, just edit the addition sentence and move the dot on the line and change the start number font colour.
Hope they help children learn addition using a number line.
Good luck from Cambodia.

PLUS: Counting in the stars by 2s or 5s with fireworks 2,4,6,8 who do we appreciate? The underpaid teacher!!!
DIY visual subtraction
Simple idea, simple worksheet. Students enjoy it.
Grid format. In the space next to the subtraction sentence students draw what they like (simple circles? Sweeties?) and then cross out how many they need to take away, then count the remaining objects and write the answer into the sentence.
Easy to edit.
Math Word Problem Anchor Chart
Simple math word problem poster / anchor chart for addition and subtraction word problems for KS1 learners.
Times Table Speed Card Sorting Game
Simple against the clock sorting game for students to practice times tables.
Print onto card and get students to cut them out.
To play the game:
1) Turn cards upside down and mix them around
2) Begin turning them over and sorting them into the correct order when the stopwatch starts.
3) Record your time for each day of the week.
4) Keep cards in an envelope ready to play the following day.
I print one set for each pair of students in my class and they play as a teams against the other students in the class. (cooperative, social constructivist learning etc.) But can also be used as an individual fast finisher game.
Provided are cards for the 4 times table, as that is what my class are learning this week, but very easy to edit for any times table.
Provided three versions:
one with the 'x symbol, multiplicand. & = symbol' on one card (least number of pieces) [this version also includes 4 wrong answers to make it a little more difficult] ,
one with 2 digit product on one card (harder),
and one with each digit on separate cards (hardest, and also easiest for them to lose cards of ;-))
First Tally Chart
Simple tally chart recording. Stars, Hearts, and Smiley faces. Cross them out, tally them, record the total. With key.
Division and Multiplication / Combining and Sharing Objects
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.
