Activity
This game gives students practice in adding one-digit number facts to two-digit numbers.
The students record a cumulative total as they go. Encourage them to do this mentally before recording the new total and suggest that other players also confirm the score. They will need to avoid being jumped while, at the same time, trying to score the highest points. As a variation, you could change the target number to 150 and use numbers between 13 and 19 in the circles.
