Read math riddle book Grapes of Math by Greg Tang. If you are pressed for time, it is not necessary to read the entire book. Just give enough opportunities for students to hear some of the math riddles and discuss possible ways to group items to find the total using mental math. Place the book in a math center with directions to allow students to find all possible ways to group to find the sum. Students may journal the prompt: Discuss how changing the grouping allows the sum to remain the same or change. This lesson may be used as a discovery lesson for associative and commutative properties of addition. This idea was borrowed from teacher Shannon Kent at Smart Books.
Create a math computer station with Steve Miller’s Math Riddles. Many opportunities for students to participate with different levels of difficulty (mentioned on Math Munch).
Leave a computer open for Math Munch. Today they explored partitions. This was a WOW concept for me and I think some students would be enthralled by the video led by mathematician, James Taton, explaining how breaking down Fibonacci numbers into partitions creates another Fibonacci number. As mentioned earlier this week, it is the pursuit of the play with numbers that will make students more comfortable with math.
