Math Fun: Puzzles and Games
updated April 27, 2018

Recorded here is my own personal collection of articles, resources, favorite links, teaching ideas, and lesson plans. It encompasses many years, from the very beginning of my experience studying and learning about Waldorf to the present time. People from all around the world visit my site and recommend it to others. Welcome!

This site records my journey. I hope my honesty is encouraging and helps break down some barriers that may prevent people from trying Waldorf methods. Because this is an ongoing site documenting my curriculum planning and ideas, some materials are more Waldorf-y than others. Please feel free to take what you like and leave the rest.

I prefer to have three MLBs for each subject and so I created "Math Fun: Puzzles and Games," in addition to the traditional second grade "Column Algorithms" and "Shapes & Number Patterns."

Without exception, I would recommend Jamie York's excellent book of math puzzles and games for grades 4 - 12. However, even as early as grades 2 and 3, I know students want a fresh challenge.

This block could also be used as a transition in the Summer between 2nd grade and 3rd grade.

Here are my notes:

Introductory Games

Dice Game

Crocodile Game

Hundred Board and Control Chart

Spatial Puzzles

Turn the Fish
requires 8 wooden matches; draw the original diagram on the board so that students can return to the beginning when trying again, or after solving it

The Farmer and His Ducks
I think this one is easiest if you draw it but you could also have gems handy

Coin Triangle (here is the solution)
I set up two of these on rimmed wooden trays so that multiple people could work on the puzzle at the same time, and I drew the starting arrangement on the board so that they could return the coins to the beginning configuration after solving it

Trees in Rows (here is the solution)
have a box of gems handy and a piece of plain white paper for each child to set the gems on to reduce visual clutter; if people are still working on the Coin Triangle puzzle, you can have them re-use the wooden tray and 10 nickels to solve Trees in Rows

Note: if you did not already do them, there is a list of Geometry and Spatial Sense activities at the end of the Shapes & Number Patterns block page

Logic & Computation Puzzles

Ghostie Numbers

Magic Triangle 1 - Magic Sum 9
scaffold this by giving struggling students the position of two of the numbers; this site also includes other magic triangle puzzles (with sums of 10, 11, 12, and 17)

Farmer Brown and Farmer Green
have a box of gems handy; scaffold this by letting struggling children know that both numbers are less than ten
