In Your Math Notebook:

Let’s get out our math journals and  work through the following application problem. Make sure you read the problem carefully, draw a picture to match your thinking and write and solve an equation.

Read, Draw, Write. DONE!

R (Read the problem carefully.) The art teacher is making a rectangular mural on the wall to display the square tiles that we painted. If there are 24 painted tiles, what could the dimensions of the mural be? Is there more than one way that she could display the tiles? Explain your thinking with pictures, numbers, and words. D (Draw a picture.) W (Write and solve an equation.)
