Math Inspectors 4: The Case of the Hamilton Rollercoaster [Kindle Unlimited] — Daniel Kenney, Emily Boever (16 titled chapters) December 17, 2019
One of the shorter reads in the series yet reads at the same space, or slower. Lots of illustrations and Pythagorean theorems…and personal tests for each of the team members.
Someone has decided to blow up the town’s amusement park roller coaster unless the Math Inspectors solve a series of riddles to retrieve the key to stop the bombs from exploding. Each riddle pushes each member to the limit of their “fears.” Going through these personal stress tests, the reader learns more about each of the characters stumbling blocks from their past.
Another fun mystery involving math.
Best to read in order as each one builds upon the last story. “Do You Have What It Takes To Be A Math Inspector” has five more word puzzles. Great for all ages!
Five stars.

The Math Inspectors is a fun kids mystery series, but book 4 definitely gets more serious. The arc which runs through the books is starting to get more noticeable to the kids, and will continue through at least the next one. So, I’m intrigued, and definitely want to keep reading.

Really enjoyable read ( series). Feel like you really get to know the characters like friends. They seem like kids you know and would hang out with. Fast pace, fun t
Reading! Can't wait for the next book. Even made math interesting and explained the math so you could follow along.
