Fact Triangles:

The dot shows the Product-this should be the biggest number

The bottom numbers are the Factors

If we are dividing then 40 becomes our Dividend

The bottoms numbers then become the Divisor (the number doing the dividing) and the Quotient (the answer to a division problem)

Looking at Data

• Maximum-The Biggest Number

• Minimum-The Smallest Number

• Range-Max - Min

• Mode-The number that occurs MOST Often

• Median-The Middle Number

• To Find Median, Line the numbers smallest to largest and then Find the Middle

Open Sentences

• Variable: a letter/symbol in place of a number

• Solve by reversing the equation

• ALWAYS Check to make sure it works!

• Remember: $=$ means Both Sides are the Same 

  
  

Multiples in a Venn Diagram

One side multiples of 3, one side multiples of 5. The middle has multiples of both. Multiples of neither go on the outside.
