Multiplication (12/15 thru 12/21)

We explored multiplication tables with grades 2-5 beyond the standard 10x10 table.  These included powers of two, unit fractions, prime numbers, even numbers, and standard tables up to 30x30. Mathletes should work at their own pace with as many of the tables with which they are comfortable. The answers are provided after each blank table.  Do not print out the entire file as it is 19 pages.

Doubling, Powers of Two, and Binary Numbers (12-8 thru 12-14)


This week we practiced doubling numbers from 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, and so on.  The children were able to recite the first ten numbers in this sequence in less than 10 seconds. They should practice that sequence this week; and the ambitious Mathletes should try to double 30 times (see the attached worksheet).

Building with Bendaroos and More (12-1 thru 12-7)

This week the Mathletes created two and three dimensional figures with Bendaroos (colored wax sticks) including: 2-dimensional - circles, square, equilateral triangle, isosceles triangle, right isosceles triangle, rhombus, pentagon, hexagon, trapezoid, parallelogram,  decagon, and septagon; 3-dimensional - prism, cone, cylinder, and pyramid. See the attached pdf file so your child can practice with these shapes.

Fraction Capture with Dodecahedron Dice (11-24-09)

Now that you have mastered Fraction Capture with six sided dice, try it with 12-sided dice.

This game is much more complex but very rewarding.  The worst roll on the board is 1 and 12 for 1/12 and the best roll is a 2 and 11 for 11/2.

You will need to create two 12-sided dice to play this game.

The attached file has the directions, the advanced game board, and templates for dodecahedral dice. Print the templates on card stock, cut out, fold, and  glue/tape.

Have fun and a happy Thanksgiving.
