Grade 1 Learning - numbers that make 20

This week we were learning about combinations of numbers that make 20. Students were assigned a one-digit number and a two-digit number that together makes 20. We used Grilles de Dix (ten frames) and Doubles Grilles de Dix (two 10-frames) to represent the assigned numbers. An example is below. Questions we ask are "is it more than 10/20?" (Est-ce que c'est plus de dix/vingt?); "is it less than 10/20?" (Est-ce que c'est moins de dix/vingt?); and "How much more/less than 10/20?" (C'est combien plus de/moins de dix/vingt?)
