What Do You Notice? Number Wheel

What Do You Notice? Number Wheel


Skills:
K-2: number recognition, counting, geometry
3-5: addition/subtraction, patterns, odd numbers


This is a fun puzzle where the main objective is to figure out where the three missing numbers of the “spokes” are placed. Since the numbers 1, 2, 5, 6, 7, 8, and 9 are visible, the missing numbers would be 3, 4, and 10 (assuming we are using the consecutive numbers 1 – 10. There is an alternate solution for the missing numbers 0, 3, and 4 which is described below).

Younger students may notice a circle, a square, and (10) “triangular” pie pieces. They will probably notice that some of the spokes are missing numbers. Starting at 1 and counting on, they may discover the three missing numbers: 3, 4, and 10. It would be interesting to ask them where they think the numbers go on the wheel and why they chose those specific spokes.

Older students will quickly notice three missing numbers. With a little bit of guidance, they should be able to notice some patterns that can help them determine where the missing numbers should be placed.

Time Capsule – A Family Math Night Activity

Time Capsule – A Family Math Night Activity

We are living through a historic moment in history that has brought about some major changes to our lives. As an elementary math educator, I wanted to figure out a way for students to capture this moment through a math activity. That’s when I came up with the idea of creating a time capsule.

I presented the activity a few weeks ago as a webinar for a homeschooling consortium but when we lost the video of the presentation, I decided to film it again and am including it for you below.

It’s a simple but fun project that the whole family can do. With a little adaptation, it would work in the virtual classroom, as well.

Family Math Night Home Edition – SPANISH version

Family Math Night Home Edition – SPANISH version

I’m excited to share with you that the PDFs for all the Home Edition activities have been translated into Spanish. A HUGE thank you to Carley Beale and her staff from Virginia for taking on the project! They did an amazing job. Click here to access the PDFs which can be found listed under the video once you click on an activity.

As I described in my Family Math Night Home Edition post, my goal was to design the Family Math Night/Day to be different than simply doing a math activity at the kitchen table. It’s their own personal event and I walk them through how to do it step-by-step. And now our Spanish community can join in the fun!

I hope this helps you keep families engaged in discovering the wonders of math together during this time of continued uncertainty.

Family Math Night Home Edition

Family Math Night Home Edition

Family Math Nights are usually done at school but I created one that families can do at home. This comprehensive resource includes video tutorials, check lists, materials lists, and activity sheets for four home-friendly activities for grades K-5. I’m including the video below.

My goal was to design the Family Math Night/Day to be different than simply doing a math activity at the kitchen table. It’s their own personal event and I walk them through how to do it step-by-step. Watch the video below for tips on making it a special event.

What Do You Notice? Lego Blocks

What Do You Notice? Lego Blocks


Skills:
K-2: counting, subitizing, geometric shapes
3-5: skip counting, repeated addition, multiplication, beginning algebra


Although there are no numbers represented, this What Do You Notice? poster is filled with number concepts. Young students should be able to quickly recognize that there are 4 circles on each square (subitizing). From there, they can decide how they want to count circles. Maybe they want to count just the circles on the pink squares or blue squares. Or maybe they want to count all the circles to arrive at the total number. Others may notice the squares and decide to count how many squares there are all together.

Older students can use repeated addition to determine the total number of squares (4 + 4 + 4 or 3 + 3 + 3 + 3) or they can multiply 3 x 4 or 4 x 3.

There are a variety of ways these students can determine the total number of circles: skip counting by fours; determining the total number of circles in a row and multiplying that by 3; multiplying the total number of squares by 4, multiplying 6 circles x 8 circles, etc.
