Remember When We Celebrated Leap Day?

Did you know that 2020 was a leap year?  At the end of last month, we celebrated leap day in K/1 math by building collections of 366 objects! 

Counting collections of all types is a great at home learning activity for all ages!  I bet you have a lot of great things you could count.  I wonder if you have 366 of anything!

Here are some of the collections the students built.

One group used Digi Blocks to build 366

These kids used base 10 blocks!

That is a lot of number racks!  If you need a number rack to do math at home, you can use this one on your computer, tablet or phone.  It's free!

Unifix cubes were a fun way to build 366

These kiddos used straws.  Rubber bands and hair ties helped them bundle groups of 10 and groups of 100.

These students used dice.  They used the green bins to hold groups of 100 and the orange cups to hold groups of 10.  Don't forget to count the 6 dice all the way to the right!

Is there something at home that you can count 366 of?  If there is, take a picture and send it to me so I can share it on the blog!

FLASH games not working on the blog

I have had a few emails about games not working on the blog.  Some of the games use FLASH player and this video shows you how to make sure it is on when you are on a Chromebook.  FLASH games do not work on tablets or phones.  There should be plenty of games that do work on all devices but all games should work on your Chromebook.  Here is a quick tutorial to show you how to make sure FLASH player is turned on. 

Arrays in Real Life

How are you doing with learning from home?  To help you out with some real life math fun, I wanted to share with you some pictures that were taken at school over the last few months of real life arrays.  Arrays are objects arranged in equal groups and we can use counting, addition or multiplication to figure out how many. 

Here are some real life arrays that I found this year at school and in the real world.  Can you figure out how many in each picture?  I have turned comments on for the blog for now so feel free to submit your answers!  Comments will not appear right away, I have to approve them first!

How many eggs can fit in this carton? 

How many number cards does this student have on the floor?  (Who got number cards in their math box for at home learning?  Have you showed your parents all the things you can do with them?)

How many slits in this ACS heater? 

How many tiles on this section of the ACS kitchen floor? 

I took this picture at Castleton State University.  How many window panes? 

Kids in grades 3-6 figured out how many window panes in this skylight in Union Station, Chicago back in December.  (You can't see the entire thing in this shot!) 

If you want to share your answers, you can in the comment box below!

Can you find a real life array at your house?  If you want to share it with your classmates, I will post your real life arrays to the blog.  Send them to me in an email! (ttrudo)

Learning From Home

As we transition to learning from home, please feel free to keep using our school wide math blog to practice math.  Pages for each grade level have been recently updated.  All grade level pages include songs, stories and games to review concepts we have taught this year.

Many of our students are in multi-age math classes and have permission to check out games on both grade's pages.  Kids can find the pages that work for them by clicking on the grade level at the top of this page.

Additionally, there is a page labeled F this is full of fraction practice.  This is is great for kids in grades 4-6.

The G page is also available.  This page is full of geometry practice for grades 3-6.  It is a great time of  year to review important geometry concepts!

We will continue to keep you informed about other learn from home activities.

Paper Fillers: 3 Act Math Class

How many pieces of paper do you think will fit in the bin?  Write an estimate you know is to high, write an estimate you know is to low.

Act 2

Act 3

Coin Counter

One of our sixth graders recently got a coin counting jar and made this three act math task for you to solve! This task was inspired by the work of Graham Fletcher and his three act math tasks.

Act 1

What do you notice? What do you wonder?

Act 2: The total amount of money in the jar was $2.00
