What children learn in Level 26
- The 2s facts are doubles! 2 × 8 is 8 + 8, which is 16. Every product of 2 is even.
- The 5s facts count by 5s, and always end in 0 or 5. 5 × 7 is 35.
- The 10s facts are tens: 10 × 6 is 6 tens, which is 60. They always end in 0.
- Notice: 5 × 6 is half of 10 × 6. Half of 60 is 30!
