Multiplication Estimation
Josh the giraffe loves to be able to quickly guess how many people are in a room, how many cars are in the street, how many boxes are on the shelf, or even how many seagulls are on the beach. Often, when he is trying to solve a puzzle, he doesn't need an exact answer, just an answer that is good enough. Estimation can save Josh time, money, and helps him make fewer mistakes. Let's help Josh practice some estimation with multiplication.
