Grade 6 Rocks Visual Patterns

I’m always happy to hear how teachers use visualpatterns.org with their students. Michael Fenton shares how he uses the patterns with Desmos. And this. Alex Overwijk’s students use the big whiteboards.

Reversing the Question

Don Steward posted this on Sunday. Like Don, I really like this task and also think it has a certain Malcolm Swan je ne sais quoi about it. I showed only the top part to my 6th graders, and I gave them 2 minutes to write down what they notice. In addition to noticing the given information, the students also mentioned: […]

Four Square and Other Questions

One afternoon during recess I noticed that the Four Square grid at our school had been enlarged. Naturally I yelled out to the kids, “Hey kids, when did they make this larger? I wonder what percent increase this is. What do you think?” Taking a nanosecond pause from their game, they yelled out their estimates, anywhere from 50% to […]

Multiplication: Finding the Greatest Product

From a set of 1 through 9 playing cards, I draw five cards and get cards showing 8, 4, 2, 7, and 5. I ask my 6th graders to make a 3-digit number and a 2-digit number that would yield the greatest product. I add, “But do not complete the multiplication — meaning do not figure out the […]

Two Pizzas and Five People

I’m thinking a lot about how my 6th graders responded to a pre-lesson task in “Interpreting Multiplication and Division” — a lesson from Mathematics Assessment Project (MAP) . MAP lessons begin with a set structure: Before the lesson, students work individually on a task designed to reveal their current levels of understanding. You review their scripts and […]

First Two Days of School

Tomorrow is the day. I’m excited to meet my new Math 6 students — all 71 of them, two classes of 36 and 35. I should know about half of the 33 Math 8 kids because I taught half of them in 6th grade. Then I get a big break in class size with just 9 students in […]

Rates and Proportional Reasoning

I’ve been hyper focused on “rates” and “proportional reasoning” for a project I’m working on. Not that one has to look far and wide either, unit rates and proportions are all around us. We intentionally and inadvertently compare things. (HA! I didn’t even realize what this product was until I’m cropping and re-sizing them for this […]

Discount and Sales Tax

Instead of doing the above exercises in our textbook, I had my 6th graders do this: Shopping Contest at Target Let’s pretend Target has a contest. The contest is for shoppers to find merchandise from their online store. Contest rules You must choose at least 10 different items. The items must come from at least 5 […]

Prices, Proportions, Percents

I was in Garden Grove with my son on Sunday, and he insisted that I try this smoothie place called Tastea. With Jamba Juice and Blenders and all the other juice bars around town, I was skeptical that this joint’s concoctions would be anything different. He ordered a taro milk tea and I got a Thai […]
