1 More 1 Less Worksheet Scaffolding and Extension Tips
In addition to individual student work time, this worksheet can be used for:
- Guided math groups
- Classroom math station/center
- Pre-lesson knowledge assessment
- Post-lesson exit ticket
- Whole-class review (via smartboard)
Got fast finishers? Challenge students who have a grasp on the concept by encouraging them to practice with 2 more and 2 less and/or 10 more and 10 less.
For students who need more support with adding and subtracting 1, provide manipulatives like connecting cubes or base 10 blocks to help them visualize the concept. Students can also refer to a hundreds chart or desk plate.
