Watch this video. After you have watched it could you have a go at making some arrays with objects in your house? You could use lego, pencils, pieces of pasta. Have a go at making arrays in lines of 2, 5 and 10. Then count in these steps to see how many you have altogether!
Do you have some dominoes at home? Could you have a go at finding the dominoes that have the same spots on each side? What is the total of both sides?
Choose an amount of something you have a lot of (pasta, lego, building bricks). Now double it!
