You may have noticed that some of the Mathematizing Story Maps look alike.
You’re right.
Have you ever noticed that a bar model feels like the “right” diagram when you map out an Additive Comparison problem like the two Alices below? But somehow that same bar model feels different when you map out an Add-To problem situation?
You’re right.
The Add-To situation requires action. Something’s got to happen for it to look and feel “right,” like the fruit counting situation below.
Lanie is removing the fruit from the colander. She removed 5 fruits and had 2 left. How many did she start with? Follow the arrows to find out!
After drinking the first potion, Alice was suddenly 9 1/4 feet tall. She drank from another bottle and grew to 15 1/2 feet tall. How much did she grow after the second bottle?
More Mathematizing Story Maps Coming Soon!
Each Tuesday we release a new set of Mathematizing Story Maps, one for each problem situation seen here. This week we summarize all of the addition and subtraction problem situations, creating two broader categories: Active and Relationship categories.
Be sure to check out the page summarizing Add-To and Take-From problem situations!
Next week we share a set of Multiplicative Comparison problems situations that help students learn to model their thinking.
