By Mr. Bales

2. Objective
By the end of this lesson, you will be able to solve problems using the look for a pattern strategy.
Standard 4MG3.0 - Students demonstrate an understanding of plane and solid geometric objects and use this knowledge to show relationships and solve problems.
Standard 4MR1.1 - Analyze problems by …..observing patterns.

3. Introduce
Chloe gave her sister 4 hats last week. She gave her best friend 2 hats yesterday. Chloe’s mom gave her 5 new hats this morning. Chloe now has 12 hats. How many hats did Chloe have originally?
What strategy would you use to solve this problem? Why?

4. Teach
Noah is helping his dad put tile on a table. They are laying the tiles in a pattern. They have run out of tiles and need to buy some more. What color of tiles need to be purchased to complete the table?
We need to UPSC - Understand, Plan, Solve, and Check

5. You know the tiles form a pattern.
Step 1 - Understand
Noah is helping his dad put tile on a table. They are laying the tiles in a pattern. They have run out of tiles and need to buy some more. What color of tiles need to be purchased to complete the table?
What facts do we know?
You know the tiles form a pattern.
You know they need to buy more tiles.
What do you need to find?
Find the tile colors that need to be purchased.

6. Step 2 - Plan
Look for a pattern. Then continue your pattern to find the missing tiles.

7. Step 3 - Solve
Noah is helping his dad put tile on a table. They are laying the tiles in a pattern. They have run out of tiles and need to buy some more. What color of tiles need to be purchased to complete the table?
There are two rows of tiles and the tiles repeat red, green, blue, and yellow.
In the first row, the missing tiles are blue and green. In the second row, the missing tiles are red, blue, and yellow.
So, Noah and his father need 2 blue, 1 green, 1 red, and 1 yellow tile.

8. Step 4 - Check
Noah is helping his dad put tile on a table. They are laying the tiles in a pattern. They have run out of tiles and need to buy some more. What color of tiles need to be purchased to complete the table?
Look back at the problem.
The answer make sense for the facts given. So, the answer is correct.
