Addition Within 20: Open Number-Line Jumps
Name:
Date:
Today I am practising: representing addition with jumps on an open number line
1
Start at 6. Draw one jump of 4 and one jump of 3 to solve 6 + 7.
2
Start at 9. Jump 1 to 10, then jump 5 more. Solve 9 + 6.
3
Draw two equal jumps to show 7 + 7.
4
A line starts at 8 and ends at 15. Label a jump plan that reaches the end.
5
Solve 11 + 5 with one jump. Why can you use a single jump here?
6
Create an addition path ending at 18 and write the matching equation.
Grown-up note: Ask your learner to explain one answer in their own words.
