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.
Inverse multiplication division for fours facts and eights facts.
Division as inverse of double-double (dividing by 4) and halve, halve, halve (dividing by eight).
Also with input-output table worksheet to use with ones blocks for 3’s and 4’s facts.
Plus multiplication - division colour matching for all facts.

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 ;-))
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.
Gold, silver and bronze certificates for students who have learnt their multiplication tables to different levels.
Also includes the reverse side showing test results (you just need to delete ticks corresponding to results to match the front side)
Comes with a checklist / test sheet.
Levels are;
BRONZE
For being able to say a complete multiplication table in order.
e.g. "One times two is two. Two times two is four etc."
SILVER
For being able to give the product of the numbers multiplied together, out of order.
e.g. Q: “What is six x two?", "What is twelve x two?" etc.
GOLD
For giving facts when presented with the product only
e.g. “24?” “12 x 2”
Please rate and comment if you find them useful.
Little test of key number line skills aimed at year 2 or 3.
Question 1: Identify numbers on a 700 - 800 number line
Question 2: Using relative position to locate numbers on a number line
Question 3: Working with relative position to find nearest 100
Question 4: Comparing and ordering three-digit numbers.
I will back to back print it on a three digit number ordering worksheet or a less than greater than worksheet.
Numbers words on a colourful worksheet.
Write each number word the corresponding number of times (e.g. write one:1 time, write two: 2 times etc)
1-10 on one page. 11-14 on one page. 15-17 on one page. 18-19 on one page. and 20 on one page.
Should keep 'em quiet for a while !!!???!!!
My class really like these: add together the two numbers at the bottom that are in the same colour box. Then write the answers in the boxes in the middle. Add together the two numbers in the boxes and write the total in the star shape at the top.
Differentiated worksheets uploaded (easy/missing numbers/DIY blank etc.) Also easy to edit.
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.
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.
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.
