This video is great because the numbers are split into groups of 10. You can fast forward to the particular group of numbers your child is practicing. I've explained to the children that while we have 1 disticnt pattern of counting in English, the French have several patterns, e.g., the base number +11, +12, etc., 4 x 20 +1, +2, etc., and 4 x 20+11, +12, etc. This video will help them practice that.
