Number Line Review: Counting and Adding for Grade 2
A slide-based review packet for 2nd graders that builds skills in counting forward and back on a number line, locating numbers and their relative positions, and adding two-digit numbers with open number lines using jumps of 10 and 1. It moves gradually from a mystery-number warm-up through guided practice, with speaker notes and prompts like "What do you notice about its neighbors?" that support whole-class discussion.
“create review slides for math skill students count forward and back on a number line. Students will analyze where a number is located on a number line and its relative position to other numbers. as well as using an open number line to add 2 digit numbers using skip counting of 10's and 1's”
Teacher Guide & Tips
- Use as a whole-class review at the start of a math block of roughly 30 to 45 minutes, projecting the slides and pausing at the speaker-note prompts so students can reason aloud.
- Discussion question: "What do you notice about the numbers next to the mystery number, and how do you know where it belongs?"
- Scaffold for struggling readers: keep a physical number line or hundreds chart at each table, and have students act out hops of 10 and 1 with their fingers before drawing jumps on the open number line.
- Extension for advanced students: ask them to build a two-digit addition problem that needs two jumps of 10 and then explain how the jumps would appear on the number line.
- Estimated time: about 5 minutes for the mystery game and 10 to 15 minutes for the addition practice, leaving time for a quick exit check.
