Day 79: Targeting 2500

20140203-150651.jpg On Target! is perfect for practice for any concept, with estimation and strategy thrown in for good measure. In this variation, played with a class of 4th graders, the target was 2500. Players select 4 cards from the deck (1o’s and face cards removed) and arrange them to create two 2-digit numbers, so that the product is as close to the target as possible.

By the way, notice the array models! I’m so proud of my teachers for incorporating this strategy into their multiplication unit.

(Yes, I know that I’m way behind on my blog. This post is from January 8!)
