Rules of Divisibility. How did we decide what they were? That’s where we are headed in our math journey at the moment. I’ve talk about going back, reviewing, revisiting, or doing an activity more than once. This repetition brings depth to our math journey. We are doing just that again in preparation for reducing fractions…

The Shapes of Numbers — Exploring Prime Numbers through Eratosthenes’ Sieve
The sieve of Eratosthenes is one of my favorite math exercises to do with kids, and it’s a great intro into prime numbers. It eliminates numbers through the multiples, leaving primes on the 100 chart. We usually use block crayons, because there is a definite pattern on the 100 chart for multiples, and block crayons…
An Inside Look into our Homeschool Math Journal
Some homeschoolers keep a common place book. Some homeschoolers keep a language arts book. We keep a Math Journal. Because I’m not teaching math from a curriculum, keeping a math journal helps us to keep track of where we have been and thus where we are going. When we are stuck on a challenge, we…
Comparing Rods for Fractional Relationships
In this activity we are comparing each rod to each of the others to see the fractional relationship. It looks overwhelming, but it’s not. The first couple of rows or columns are the most challenging and after a pattern emerges, and it becomes much easier. Having said that, this comparison did take us three to four…
Patterns in the Multiplication Chart
*A note about the numbers. In this piece to try to keep things clear, when I speak of the multiples or a particular number, I am writing the numeric symbol for the number i.e. “9.” If I am not talking about the number but describing an amount, I am spelling it out i.e. “three…
Turtle Tessellation Tiles and Pentagon Spirals
We are finished with our homeschooling year. Well…almost. We didn’t get to math this year, and so as we shift our focus to more fun, and a less strictly academic theme to our schooling (because who are we kidding? Homeschooling is a lifestyle; there really is no “summer break,”) we will be doing our math…
