We began 'Showing the Money' with a free app called Coins. This was also the title to a song we listened to where the children had to hold up the appropriate coins along with the song.
For this practice they are shown cards or are told an amount and then asked to show at least 2 ways to make this amount combining different coins. We have been doing this daily during our calendar math period which the children can now do with the app along with me or independently.
This first day they were taught how to take a screen shot so I could show off some of their work!
