For those who follow our multiplication adventures, here are more details. The next multiplication-centered event for parents will start with parent questions. Think of it as a citizen science project of the action research type. Action science is for a community solving a current problem using scientific tools. Together, participants collect data, analyze the data, implement the changes the analysis suggests, collect more data on how those changes worked, and so on – until great solutions to the problem emerge.

We invite you to tell us what you and your children want about multiplication – and to figure out how to make these dreams come true! Depending on the level of community interest and support, the study may produce some or all of these results. As with all our projects, the results will be shared with the world, under a Creative Commons open license.

One of our most popular Pinterest boards is Eat Your Math. Check it out, and send us links or ideas for more tasty math activities!
Meet our newest blogger, pen name Marina Mersenne (check out the history), debuting with 3D Illusions with Easy Grids. Children often ask how they can create their own illusions. Your children can start with these art project ideas, and then experiment with other shapes and grids!
In the Math Mind Hacks series, check out Guesstimate. After I made the mini-poster, Sheryl Morris commented on our Facebook page that it would be nice to make a version for the Montessorians. The proof of concept comes from research of cognitive neuroscientists Park and Brannon, from Duke University.
We took part in the 70th monthly Math Teachers at Play blog carnival – a big collection of family math activities. For example, Mashka introduces her preschool/kindergarten math circle to thinking about systems in Tricky PreK Math, Lesson 8 – Year 2.
Take a huge loop of yarn (the size of half a room) and ask the kids to hold it at any place. Then tell them to close their eyes and that if they peek, the game will not work. Then, tell them that with their eyes closed, they have to make a square with the yarn. They are allowed to communicate with each other. Try it multiple times and see what happens! We only had a couple of minutes to play, but it came out very funny with everybody tangled. Almost all of them were cheating (their eyes were open) and they still couldn’t make a square (or even get untangled).
We have a playschool group with kiddos 0-5, with moms, and were thinking about acting out function machines with one mom in a box and we hand her input (toys, numbers) and she give us output (altered, increased, decreased). Has anyone done something similar and can you recommend what props are good to have on hand to make this fun?
- Boxes with both ends open, or tubes (you can just tape paper into a cylinder) are more fun to use than a flat Function Machine drawn on paper.
- Heads up: young kids want a new function machine for every new function they make up, or you make up. For older kids, the same diagram or just the letter F can stand for different functions, and the same prop can represent different machines. Little kids won’t like that, at least at the beginning. Later you can introduce a magic wand or a wrench that kids can use to change and modify your old function machine they already explored into something new and exciting. You can use a pencil to pretend-play that tool, or bring a strange-looking shop tool or utensil for your prop.
- Food you can slice, such as apples, works great for machines that cut things into halves or other parts. Raisins are nice if the machine houses something like Purple-Tailed Raisin Eater, who always swallows two of the raisins that enter and no more.
- Playdough or soft modeling clay can create interesting machines. You can slice it, stretch it, squish it for a variety of 3D transformations.
- Small stickers or cards plus large markers can be props for coloring machines that turn everything that enters green, red, or polka-dotted.
In general, think of machine rules ahead of time, and how you would pretend-play them!
We have several activities in the Moebius Noodles book, which also has some suggestions for prompts.
I am leading a semester-long online course at Arcadia University. As usual for the courses I design, all course assignments will happen in live online communities, and people who are not at Arcadia are welcome to participate. You can view the syllabus and jump right in with the first assignments! Here is the plan, by weeks:
8. Maria’s topic of interest: algebra and calculus for very young kids
9-14 Your topics of interest (to be determined in earlier weeks)
15. Summaries and farewells
You are welcome to share the contents of this newsletter online or in print.
Talk to you in two weeks! Moby Snoodles, aka Dr. Maria Droujkova
