This activity is designed to help students use the 120 Chart with the Number Puzzles to determine what number comes before or after a selected; what number is 10 more or 10 less, etc. There are two puzzles with the numbers inserted for you and two puzzles that are blank so you can fill in the numbers yourself.
Love it! Our math series is not at all aligned with CCSS, so I'm looking everywhere and making lot of my own lessons. These are great. Thanks so much!
Check out my store for some 120 chart pictures.
I have been a teacher for 11 years. Teaching is my second career and the BEST job I've ever had. I worked in the business world for 20 years before finally doing what I've always wanted to do in the first place!
