Practicing with the 100's chart is important for building number sense. During this activity students will read the number clue and color in the answer on the 100's chart. The picture has three different clue sets. The first clue set builds only on the concept of one more and one less. The next clue set for the picture is 10 more and 10 less. The last clue set is a combination of 1 more/less 10 more/less. You can select the clue set that meets your students' needs. Each clue set has an answer key as well. This is just the first 100's chart activity of a complete picture set that will be differentiated. ENJOY!
