I created this worksheet for my students to practice adding 2-digit numbers using a 100 Chart. They can begin at one addend, and hop on the 100 Chart using various methods and strategies to add the 2nd addend to ultimately get the sum. In the box at the bottom, they can record their answer and also show how they hopped on the chart. For example 45 + 23 = 68 45 + 20 = 65 + 3 = 68. There are 2 sides with 4 problems total. I also have this available for adding 3 digit numbers. Can be used for guided practice in a whole group or small group, seatwork during math centers, homework, morning work or a quiz/assessment. Enjoy!
