This week, the children played a game to close the topic Multiplication Table of 4, 5 & 10. It is similar to a popular game Twister. For simplicity, the children only need to use their hands and/ or feet to touch the answer to the mathematical sentence. The shower curtains are bought from Daiso.
First, we need to understand the question. Not all questions will always be telling you the 'groups' specifically. For example, there are 5 groups. Each group has 2 children. How many children are there altogether? We need to identify the 'number of groups' in this question as '3 baskets'.

Cuisenaire rods will be used to show the 'group and item' concept in multiplication for model drawing. Each coloured rod has a specific length. For example, the white rod stands for 1 unit and the red rod stands for 2 units and so on.
Let me use an example from the workbook to illustrate how we relate it to their work:

We can use 1 white rod to represent 1 mango. Start by showing the 3 groups of 5 mangoes using only the white rods. Next, we look for another coloured rod that has the same length as the 5 white rods. We choose the light green one. How many light green rods do you think we will need for all the 15 white rods? Right, it is 3. So, we end up arranging 3 light green rods from end to end.
Finally, I showed the pupils how the model drawing will look if drew the conventional way (picture below). Most children are able to tell me the purpose of model drawing for Multiplication. Why drawing the conventional way for Multiplication is not recommended? Find out from your child.
