Add a 2-Digit Number and 1-Digit Numbers: how to help at home or in class
Start with a two-digit number such as 46, roll three dice, and add the dice to it. Challenge your child to hunt for two dice that make 10 first, because 46 plus a 6 and a 4 is simply 46 + 10. Time a few rounds and watch the speed improve as they get better at spotting ten-makers. They are ready for stacked columns once they stop adding one small number at a time.
