Math Module 4 Information Page
Now that we have used base ten to multiply and divide; let's move into Common Core's Module 4.  We will dive into the Geometry domain by being introduced to the relationship between points, lines, line segments, rays and angles. We will also return to the Measurement domain by measuring angles with various protractors.

Word Problems using a Bar Model (aka Tape Diagram) and the RDWW strategy we use in class:
ead the word problem & extract (underline) the information needed to solve the problem
Draw picture to represent the problem
Write a number sentence horizontally to represent your drawing
Write an explanation of your answer to check for reasonableness
Word Problems using a Bar Diagram & RDWW This strategy is used throughout the
