Make a model to show the sums of 10.

• Lay out 10 counters in a row. The counters could be anything—pennies or macaroni or dice or little cars.
  

• Move 1 counter over to show 1 + 9 = 10.
  

• Move another counter over to show 2 + 8 = 10
  

• Move another counter over to show 3 + 7 = 10
  

• Continue until you have moved all the counters over to show that 10 + 0 = 10.

Make a poster to show all the sums of 10.

The card game Tens (Activity 30) will give lots of practice with these addition facts.
