Sunday evening, December 6th, is the first night of Hanukkah this year. I think it was much later in December last year. Why isn't it always on the same date? Students look at the Hebrew calendar and appreciate the incredible mathematics involved in creating a calendar that aligns both the moon's rotation about the Earth and the Earth's rotation about the Sun.
Stress reducing coloring and Fibonacci
Have you seen the new coloring books?
Fibonacci lattice | Golden spiral | Pentagram and Golden triangles |
I think they can be beautiful. Evidently people who like to multitask can find a means of calming their energies and reach a peaceful place by simply coloring designs. Coloring in these drawings allows you to relax and just create pretty images without worrying about being artistic or the stress that a blank canvas might bring you.
Pre-Thanksgiving activity ideas
Macy's Thanksgiving Day parade - Students study a map of the Macy's Thanksgiving Day parade, describe, measure and hypothesize why this route was chosen. Then they calculate how long each band will be marching and what time they will arrive at the finish. Students even approximate the volume of two parade balloons including Angry Bird, Red, and from two year's ago, the Wizard of Oz balloon. 4.NBT.4, 4.MD.1, 4.MD.2, 5.NBT.6, 5.MD.1, 5.MD.5b, 6.NS.3, 7.NS.3, 7.G.1, HSG.MG.1
Not enough mashed potatoes
Using his famous mashed potato recipe, Brian has asked students
- to change decimals to fractions,
- to calculate ingredient measures for various-sized Thanksgiving gatherings,
- to explain their thinking in calculating these figures
- and to judge how many servings could be created from 7 ½ pounds of potatoes.

We had a great time presenting at the NCTM conference in Nashville this morning. Here is a pdf of our powerpoint presentation. Fun!
Macy’s Thanksgiving Day parade, 2015
Students study a map of the Macy's Thanksgiving Day parade, describe, measure and hypothesize why this route was chosen. Then they calculate how long each band will be marching and what time they will arrive at the finish.
Students even approximate the volume of two parade balloons including Angry Bird, Red, and from two year's ago, the Wizard of Oz balloon. Very fun and timely with lots of Common Core standards addressed. Try the whole activity or any of the different tasks in the activity with your class.
