If a fact family has only 2 multiplication and division sentences, What do you know about the product and dividend?
How many fact families with a dividend under 100 contain only odd numbers ? You can use a multiplication table to help you.
The fact families 2*3= 6 and 2*10=20 both contain exactly three different digits. How many other fact families with dividends under 100 contain exactly three different digits? Name one muliplication fact in each of these families.
Maria made 5 different figures using the same 6 tiles . Do the figures all have the same area, different areas, or are you unable to tell?
