Mathematics - Addition and Subtraction - Addition within 20 - Adding Past 10

5 steps: (1) Review: 5+3=8 (stays within 10, easy!). (2) What about 8+5? The answer is MORE than 10! (3) Strategy: Break the smaller number to 'fill up' to 10. 8+5 → 8 needs 2 more to make 10, so 5=2+3, and 8+2+3=10+3=13. (4) Show on double ten-frame. (5) Three more examples worked through: 7+6=13,
