In fourth grade, students are expected to master the basic multiplication facts 0 - 10 by the end of the year. As many of you know, this can be extremely difficult for a lot of children (and adults).
One of the things I learned at my math conference is how important it is that students have a basic understanding of grouping. Believe it or not, many students have just grasped the idea that the number 3 represents three items such as three McDonald cheese burgers or 3 toys. Now we expect them to put the three hamburgers together and call it 1 "group" of 3 hamburgers, but they still see it as three hamburgers-"where does the one come from?" Then, we want them to know that 3 groups of 3 hamburgers is 9 hamburgers altogether. I can see how it could be very complicated to a young mind.
To do well in mathematics, students have to understand what is behind the numbers, what numbers represent and how they are related to each other. This week we are "assessing" the students' understanding of groups and how groups and numbers are related to each other (it's also in their homework).
It would be great if you could help your child see how things come in different groups. A carton of eggs can be seen as 2 groups of 6 or 6 groups of 2, saying 1 group of 12 may not help them see the groups since they can count the eggs one-by-one to find 12. Once they seem to have the hang of grouping, then you can move them on and ask them questions such as, we have 2 groups or 6 which is the same as 6 + 6 which is the same as 2 x 6 or we have 6 groups of 2 which is the same as 2 + 2 + 2 + 2 + 2 + 2 which is the same as 6 x 2, which would be the easiest -quickest- and most efficient way to find the total number of eggs.
We will be working on this in class, but if you see that your child is struggle with groups (how many groups there are and how many in each group) then the activities above could give them some extra support.
