The document provides an outline for a math lesson that includes the following activities: 1. A visualization activity where students view images for 3 seconds each and write multiplication equations to find the total number of shapes. 2. A discussion about numbers that have only one array and their special name (prime numbers). 3. A discussion about numbers that make a square and their special name (square numbers). 4. A number puzzle activity in pairs where students model numbers using tiles to fit two clues about making rectangles of certain widths. 5. Completing math problems from pages 5-6 of a workbook and focusing discussion on problem 2 from page 6.

2. Quick Images: 15 min. * You will view images 4 - 6 for 3 seconds each. *For each pattern, write several different multiplication equations, including combinations with three or more numbers, to find the total number of shapes. *Volunteers to explain strategies they used to see their images and their equations.

3. 15 min *What are some examples of numbers that have only one array? *What do these arrays look like? *These numbers have a special name. Does anyone know what it is?

4. What are some examples of numbers that make a square? What do these arrays look like? These numbers also have a special name. What is it?

5. Number Puzzles: 2 Clues (35 min/pairs) *Today's number puzzles have 2 clues. * The answer must fit both clues. Clue #1: This number of tiles will make a rectangle that is 2 tiles wide. Clue #2: This number of tiles will make a rectangle that is 3 tiles wide. *Work with a partner to model some numbers with the colored tiles.

6. S.A.B. - Complete pages 5 & 6. We will focus our discussion on #2 on page 6.

7. How many Answers? (10min/pairs) What numbers did you find in problem 2 on page 6? Are these numbers factors or multiples? Do all of the given answers above fit both clues?
