We've been working on skip counting by 10s with 3-digit numbers. To my surprise, my students are doing great. I'm pretty sure the reason why is because it's taken us a long time to reach this point. We've been using a new pacing guide this year and I'm seeing amazing results because of it. If you're interested, click here to download a free sample.
Here's a fun game we played to practice skip counting by 10s:
I made about ten different sets of numbers like these and gave one set to each pair of students. When I gave the set to each group I made sure the numbers were mixed up. Their job was to unscramble the set of numbers and tell me what the pattern was. (I had a little chit-chat with the yellow group after I took the picture. Did you notice a few of their numbers are in the wrong spot?)
Once they got the hang of that, I made it a bit more difficult.
I had one student remove a number and their partner had to figure out which number was missing. At first, they left a space where the number was removed, but then they pushed the cards together so you couldn't see where the missing number was (this was actually their idea).
