Students practice subtracting by counting down from a target number in a game called Count Back Bingo.
In pairs or in small groups, players or a teacher will roll numbers on a dice. Students will then count down from their target number by the amount on the dice. The first student to cover all of the numbers on their grid wins.
Game can be modified by using larger numbers or by including a dice with more than six numbers.
The document is editable - so that you can input different numbers, create more copies for a whole class activity etc.
I used this activity with a small group of my grade 4 children who were struggling with mental subtracting and counting down to or from a number.
