A little over two years ago I started writing this post. And then the pandemic hit and everything changed. And although we’re not quite back to where we used to be – and may never be – I thought now would be a good time to finish that post. I had just hosted a fabulous Gellin’ with Geometry Family Math Night event at a local elementary school. It was an in-person event which would have been a weird way to describe it…

Virtual Family Math Night

## Virtual Family Math Night

We’ve finished! And the result is an amazing virtual event for your families where they can safely engage in an unforgettable and fun math learning experience…together. How did we do it? We created a virtual classroom that serves as the meeting place for your families. Once your families enter the classroom, they’ll be able to sign in and view the Guest Book to see who’s attending. They’ll then decide which of the 5 stations they want to explore. Maybe it’s the Estimation Station where…

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.
