Students count all when finding 1 more or 1 less.

During the next unit, begin each lesson with a minute of counting orally together as a class. When students stop counting, invite them to identify the number that is 1 more and 1 less than the last number said. Represent each question with an expression.

Students double count the first number when counting on or counting back. For example, to find the value of \(7-3\) students may start at 7, count “7…7, 6, 5, 4, 3”, and determine \(7-5=3\).

Throughout the next unit, invite students to use 10-frames and two-color counters or connecting cubes to check their counting when counting on, counting up, or counting back.

Students sort objects into groups that do not have recognizable similarities or some objects do not match the stated category.

Encourage students to play Sort and Display, Stage 1 during Center Choice Time in the next unit. As students play, ask them to explain how they chose their categories. Choose an object from each category and ask students to explain why they put it in that group. As needed, support students in creating their categories by asking: “What is something that is the same about these objects?”
