About this resource
Description
Help young learners add with confidence using this count on number line addition activity. Counting on is one of the first real addition strategies children learn: instead of counting every object from one, they start at the first number and count forward for the second number. A number line makes that strategy easy to see, because every hop forward is one more.
Children pick a Star Hop card, read the problem, and put a finger on the big orange star that marks the first number. Then they hop forward one star for each number they add and say the number they land on. They write each sum on the recording sheet and check their work with the answer key. All twelve problems stay within 10, so this addition activity fits math centers, small groups, partner practice, or a quick warm-up at the start of math time.
What’s Included
- Cover page and a How to Use page for the teacher
- 12 Star Hop Cards on two cut sheets, each with a star number line from 0 to 10
- Star Hop recording sheet
- 1st grade practice worksheet with five number lines for drawing hops
- Answer keys for the cards, the recording sheet and the practice page
Why Kids Love It
- Hopping from star to star turns adding into a game.
- The orange start star shows exactly where to begin, so every child can get started.
- Seeing the hops on the number line builds a strong picture of what adding means.
Teaching Ideas
Model one card first by hopping a finger along the stars and counting out loud. Then let partners take turns: one child reads the problem while the other hops. After the count on number line addition activity, place the cards in sheet protectors so children can draw their hops with a dry-erase marker, or ask them to make up a new star problem for a friend to solve.
