The purpose of this How Many Do You See? is for students to use subitizing or grouping strategies to describe the number they see.
When students notice that 1 less is always the previous number in the count sequence, they observe regularity in repeated reasoning (MP8).

Color 1 More or 1 Less Mat
The purpose of this activity is for students to practice using the count sequence to recognize 1 more or 1 less than a number. Students should have access to counters if needed to determine 1 more or 1 less than the given number.
An alternative version of the game is introduced in the Lesson Synthesis, which students may wish to play.

Materials from previous centers
To reinforce the learning of the lesson, students who choose the Fewer, Same, More center should use the less, same, more mat, with two sets of number cards 1–20. Students choose a number from one set of cards and place it at the top of the mat. Taking turns, each partner picks a card from the other set, decides if the number is less than, the same as, or more than the original amount, and places the card with the correct group on the mat.
Students will continue to choose from these centers in upcoming lessons. Keep the materials from each center organized to use each day.
