Over the last two weeks we will be recapping what we have learnt about our numbers to 20. We will be ordering, matching numeral and quantity, counting on and back and doubling and halving.
To count reliably with numbers from one to 20,
place them in order and say which number is one more
or one less than a given number. Using quantities and
objects, add and subtract two single-digit numbers
and count on or back to find the answer. Solve problems including doubling and halving.
This week we are going to be recapping all what we have learnt about our numbers to 20.
Count to 20 with Jack Hartman - https://www.youtube.com/watch?v=_MVzXKfr6e8
Can you help order the numbers correctly from 1-20? Which ones are mixed up? What is one more/less than a given number?
Today we are going to be matching the number to the amount. They have all been mixed up can you help to match them correctly?
Today we are going to be remembering the rules for adding and take away.
We count on and numbers get bigger for adding.
We count down and numbers get smaller when taking away.
Using number sentences can chn decide if they need to count on or back?
Today we are going to be recapping doubling and halving.
When we double it’s the same number twice.
When we halve the two groups have the same amount.
Can chn solve the problems deciding if they are halving or doubling?
