    Here is the original textbook problem (2nd grade):

    Tammy and Martha both built fences around their properties. Tammy’s fence is 54 yards long. Martha’s fence is 29 yards longer than Tammy’s. (shows picture of 2 different sized rectangle yards labeled as Tammy’s Yard and Martha’s yard)

    a.How long is Martha’s fence?_________ yards

    b.What is the total length of both fences?_________ yards

    Sparking Curiosity Instead:

    Tammy and Martha built fences around their yards. (show a visual of fences being built)

    What do you notice? What do you wonder?

    Share that Martha’s fence is 29 yards longer than Tammy’s.

    Estimate too low, too high

    Share that Tammy’s fence is 54 yards long.

    Revise estimates for too low, too high, and best guess.

    Ask students to find out what the total length of both fences is? (multistep challenge for grade 2… support kids in groups who may need to solve a explicitly before trying to solve b)
