Starter: practice subitising using the PowerPoint.
Today you will need from the resource pack:
With your child count the number of marbles by listening to the sound of each one being dropped into a tin, which encourages thinking of numbers as an abstract concept as well as an amount they can physically count. They can check their answer by counting the marbles using one-to-one correspondence. They also count backwards to count the marbles back out of the tin.
Drop 7 marbles slowly into a tin, one at time. Ask: How many marbles do you think are in the tin? How do you know? Can you check by counting the marbles out of the tin? Next, count out the marbles in front of your child. Put the marbles back into the tin, counting them in carefully together. Now take them out, one at a time, starting with 7, and counting backwards from 7 down to 0. Say: There are none left in the tin. Adapt the game by dropping different amounts of marbles into the tin (up to and including 8) and then counting them back out.
