1. Topic: Multiplication: Book: Mulitplying Menace: The Revenge of Rumplestiltskin by Calvert.
2. Topic: Many. Math Jeopardy. Here are all the questions and pictures you need to play this.
We divided the kids into two teams and played a variation of Jeopardy. The categories were Multiplication, Estimation, Patterns, Tangrams, and Algebra. The first team to write down their answer and raise their hand got to guess. If the first team was wrong the second team got 2.5 minutes to answer. If they were wrong, then the first team got one last chance to guess. This way the teams are never just waiting for someone to answer.
How did it go?
We had 4 kids this week. The younger circle was cancelled because many of the kids were out of town, so my son was the score keeper for the big kids circle.
This book has a lot of story, and little bit of multiplication mixed in. All the kids were really into it, and my daughter asked if she could have it in her room at bedtime.
We divided the kids into two teams of two, and explained the rules. I think none of the kids had ever played trivia games before, so they didn’t know some basic strategy: for example, if the first team guesses wrong, the second team should take plenty of time before answering, to be sure to get it right.
Team 1 started out by getting pretty far ahead. This is mainly because one kid was really fast on all the multiplication problems, answering all of them except the 500 point one. No one got that one…it was 101 * 37. Team 1 tried to do it by writing down 101 thirty-seven times, but they ran out of time. Team 2 tried to do it using base 10 blocks, making 37 piles of 101 each. I really thought Team 2 might realized that 37 one hundred squares makes 3700, but they didn’t.
Both teams did very well on Algebra, with several kids being very close when the right answer was given. They didn’t get to the 500 question.
Estimating was hard for the kids. The teams solved the first two by counting each object. From the 300 onward they tried to estimate, but were never close enough to score points.
The 100 Tangram was pretty hard because the kids assumed our Tangram pictures would be to-scale. We had to give a couple hints for that one. The kids did much better on the 200, 300, and 400, but ultimately the one kid from Team 2 solved all the Tangrams.
Patterns was a very close category, with multiple kids figuring out what the pattern was, but Team 1 was faster at writing down the answer. We only did the 100, 200, and 300. The 300 was the hardest: Nov, Oct, Sept, Aug. Team 2 guessed that the next three would be Sept, Oct, Nov. Team 1 realized that it should be the months backward, but ended up guessing July, April, March.
Ultimately Team 1 by a score of 1900 to 1600. Everyone was a good sport, though my daughter had started to get upset when Team 1 was pretty far ahead at the start (because they did all the multiplication problems early).
Overall this was very fun and motivating for the kids, and we’ll have to do it again!
