  1. 9 · 7 plus 2 is 9. Counting on from 7 gives 8, then 9.
  2. 9 · 6 plus 3 is 9. You can start at 6 and count on 3 more.
  3. 10 · 7 stars and 3 stars together: 7 + 3 = 10.
  4. True · 6 and 4 make a ten: 6 + 4 = 10.
  5. False · 5 + 4 is 9, not 10. So the equation is not true.
  6. 9 − 3 = 6 · 9 take away 3 leaves 6.
  7. 6 · 10 minus 4 is 6. You can count back 4 from 10.
  8. 9 · 4 + 5 = 9. Knowing this fast helps you finish a whole set of facts quickly.
  9. She counted one too few · 8 + 2 = 10, so Zoe stopped one number too soon.
