Great for a math workshop station
My kiddos absolutely love this game! I purchased Sum of 10, 20 and 100. They have only played the sum of 20 so about using benchmark’s great! I only gave it a 4 because the scoring is a little tricky and I’m not sure how they would do with it at the beginning of the year when many are still trying to master 10 facts.

Thanks Beverly. I am glad your students are enjoying SUM OF WHICH is Twenty. Be sure to try out the other games you can play as well. Directions are on the website. SO YOU THINK YOU CAN ADD is a very popular one. As for score keeping, use base ten blacks. The rod is earned for every SUM of ten and every bonus square and three cubes are earned for each file played. This also helps them to practice composing their tens and even hundreds.

Thanks for sharing.
