This jeopardy-like game has 5 categories: name the value (tenths, hundredths, etc.), write in two other forms (word form, standard form, expanded form), equivalent or not equivalent (using decimals), compare and order (use greater and less than symbols or order from least to greatest), and change to tenths and hundredths (converting decimals to fractions). Problems vary in difficulty and some word problems are also included. This lesson was ch. 2 in our 5th grade curriculum, but it can be used with other elementary classes or at the middle school for review. Great to use before a test!
The way I play jeopardy in my class to ensure maximum student engagement is by having all students write their answer on their whiteboard (could be just cardstock and a transparency). I assign teams (ideally 6 students) and each student is given a number 1-6. I call on student randomly to pick category and point value. They are given a time limit depending on the question to work with team and write down the answer on their white board (usually 1 minute on timer). When timer goes off, they have to go back to their seat and stop writing. Then, I roll a die and ask the students from each team that were assigned that number to hold up their boards. Potentially, each team could win the points. We continue until the class period is over or until game board is complete, and then tally up the totals.
