Grade 3 Math: 3.0A Operations and Algebraic Thinking: Represent and solve problems involving multiplication and division: 1. interpret products of whole numbers

Today students, you will be learning how to show and solve multiplication problems in a different way. For example, you know that 4x3=12, but today you will learn how to show and solve why 4x3=12.

Tutorial

In this video you will learn how to write multiplication expressions that represent illustrations.

In this video you will learn how to look at a multiplication problem and interpret it to draw a picture.

Students, here are a few key points to remember before you go to the activity:

- the 1st number in the multiplication problem is the number of groups ex:
**3**x5 - the 2nd number in the multiplication problem is how many objects are in each group 3x
**5** - you can look at a multiplication problem such as 5x7 and draw an illustration of 5 groups of 7 objects each
- you can look at an array or illustration and write a multiplication problem such as looking at 5 groups of 7 objects each you can write the multiplication problem 5x7=35

Students, in today's tutorial you learned how to interpret products of whole numbers or in others words you learned to look at multiplication problem and draw a picture of it and to look at a picture and create a multiplication problem. You also learned which numbers in a multiplication problem represent the number of groups and which numbers in a multiplication problem represent how many objects are in each group.

For homework I want you to make your own problem showing me what you learned. Pick a multiplication problem (make sure you know how to answer it) and draw a picture of it representing the multiplication problem. Then draw another picture that represents another multiplication problem. Use real life objects and situations when creating your 2 problems.
