Finish the factor practice worksheet (just the first side).  Be sure you try both methods – factor rainbows and factor pairs.  You can use this link to help make arrays to help you find factors.

Play the product game with a parent.

Use the paper version or you can play online as a team against the computer (click the board below).

In your math notebook (with a proper heading),find all factors of 72 and of 110.

• Space your work well on the page so it is neat and clear. Remember to write one digit per box.
• Use the “factor rainbow” strategy to be sure you haven’t skipped any factors (connect each factors to its pair).
• You should also use the divisibility rules recorded in your notebook.

Today we began to analyze the factor game by creating a list of possible first moves.

HOMEWORK DUE FRIDAY: Finish the table up to 30 if you haven’t already

Everyone now has a copy of “Prime Time” – a book full of questions about factors and multiples.  On page 10, we are answering questions about strategies for the factor game.  We’ll continue this work on Friday.

We began studying numbers and number relationships today.  Here are some of the things we already know about numbers.

We also learned the factor game.  Homework is to play twice against an adult at home.  You can also play online against the computer.
