Your child 5-11 years

Master the multiplication

Your schoolboy knows his tables? Attention, it gets complicated! Make room for two-digit multiplication, then three. Here's how it's done in class and our tips for helping him at home.

  • With a very logical progression, your child approaches the two-digit multiplication. Faced with this complication, only one solution: get organized!

When does it start?

  • From the CP, your child approaches the notion of multiplication. Most often, it is in the form of repetition of additions that he approaches multiplicative writing (2 + 2 + 2 + 2 = 4 x 2).
  • At CE1, it memorizes simple results like the multiplication by 10. It builds, uses and starts to memorize the multiplication table. One-digit multiplication is addressed in CE1, although this technique is not required at the end of cycle II.
  • In CE2, the operative technique of multiplication with two or three digits is worked out. It is reviewed throughout cycle III and applied to decimals. This is why it is important that this technique be understood from the CE2 with common numbers in common use. However, it should not be searched for excessive virtuosity.

In class, how long does it last?

  • At CE1, the one-digit multiplication is approached through problems. Your child is faced with this operation in its simplest form. The construction of the multiplication table will be the subject of more sessions starting in the second quarter.
  • At CE2as of the 1st trimester, it is the operative technique itself which is shelled. In the 2nd quarter, the double-digit multiplication appears. All this year of CE2 must allow your child to master it before entering the CM1.
