Write number sentences from word problems (add/sub)
Lesson

When we write number sentences from word problems we need to pay attention to the important language in the word problem which will help us form our number sentence. There are certain words which will tell us which operation we need to use. In the following video i'll explain in more detail with addition and subtraction, with some simple multiplication in there too.

Example Questions:
