1. You can share the amount on two plates (circles) Or 1. You could count in 2's to the given number to see how many 2's make up that number.
Adding two, two digit numbers to 100
1. First add the tens 2. Then add the ones 3. Now add the two answers together
Subtracting two, two digit numbers
1. Keep the first number the same 2. Take away the tens of the second number 3. Using that answer, take the ones of the second number away 4. You have your final answer
Dividing by 5
1. You can count in 5's to 25. Or 1. You could also draw 5 plates (circles) and share 25 dots, giving one to each plate.
Adding one digit numbers
1. Put the biggest number in your head 2. Count forward the other number eg. 8 + 5 8 goes in your head, you count on five using your fingers Or 1. Draw 8 dots and add 5 more. 2. Count them altogether
Subtracting one digit numbers
1. Put the first number in your head 2. Count back the other number eg. 6 - 4, count back for times, using four fingers Or 1. Draw the first number of dots eg. 6 dots 2. Cross out the other number eg. cross out 4
Multiplying by 2
1. Multiply is the same as 'lots of', so we can draw 2 lots of 4 dots or 4 lots of 2 dots, for 4 x 2 or 1. We can count in 2's, 4 times
Multiplying by 5
1. You can count in 5's that many times Or 1. You could draw an array. Showing 5 lots of 3 or 3 lots of 5
1. If you are doubling numbers 0-5, you can use your fingers to put the amount together Or 1. You can put one of the numbers in your head and count on the same number eg. 4 in my head, add 4 more using my fingers Or 1. You can draw 4 dots and add 4 more. Then add them altogether.
Finding 3/4 of a number
1. First find 1/4. This is the same as dividing by 4 or half and half again. 2. Once you have 1/4 of the number, you need to get 3/4 by multiplying it by 3 or adding the number three times.
Number bond to 10
1. Using your fingers show 10. Ask how many fingers are down? 0 2. Put one finger down, 1 down and 9 up. These make ten. 3. Continue with all numbers to ten.
Finding the missing number
1. We have to find the difference in order to find the missing number. 2. Using the number you have, find the different between that and the total. 3. You can count forwards or backwards, add or take-away in order to find the difference. eg. you can count forwards from 22 to 35 or count backwards from 35 to 22.
Finding the difference
1. Count forward from the lower number to the higher number Or 2. Count backwards from the higher number to the lower one
Finding the missing number
1. Find the difference between both numbers by; counting forwards from the lower number or backwards from the highest number
