I used a simple brownie mix and kept it in one piece to first explain that the cake in this tin is a whole. We spoke about that it is ONE whole brownie cake.
Next, cut up the brownie cake into 20 equal sized pieces. Then discuss that 20 pieces of brownies make up one whole in this cake tin. So 20 is the denominator for our fractions in this brownie tray.
I tried my best to keep the size of each brownie the same - point out that when working with fractions each part needs to be equal.
Then to start practicing writing fractions, use some different candy to decorate the individual brownies. I used jellybeans, coins, m&m's, and monster wrapped candy.
For example in the image below:
1. Ask students how many of the brownies are decorated with M&M's?
There are 5 brownies decorated with M&M's.
2. Ask how many brownies are in total?
3. How can we show this by writing a fraction? The number decorated in m&m's is the numerator, and the total amount of brownies is the denominator.
4. If doing this with older grades, you could also further discuss simplifying the fraction as an answer.
Then continue to do the same with different types of decorations.
And then you can also do fractions for brownies without decorations.
I didn't put icing on the brownies so that I could easily change the decorations on top and keep practicing fractions as many times as needed.

This week I'd like to share an anchor chart I made to teach addition with regrouping. I found the use of place value blocks helpful in explaining the concept of carrying the ten over.
The different colors used are intended to help highlight and show the steps throughout the process.
Step 1 - Look at the ones first!
Count the one blocks to find the total. Draw them.
In the chart example, there are 15 one blocks.
Step 2- Explain that we can't put 15 in the ONES position, so if we have 10 ones, we must regroup them and turn them into a ten block. Demonstrate that this new ten block formed from the ones is CARRIED over to the top of the other ten blocks. In the numerical form, we represent this by adding a '1' to the top of the column.
Step 3 - Then add the ten blocks together (including the carried over ten block). In the chart example we have 10 + 50 + 30 90. Or 9 ten blocks which equals 90. Take the 9 (in the tens position) to sit in the TENS position of the answer.
So, the answer for the chart example is 95! .

Counting & Ordering Numbers 1-20 Activity
For this simple activity, I labeled the numbers 1-20 on the individual Lego blocks. On the opposite side of each block, I drew the amount of dots to represent the number (optional).
Once ready to begin the activity, spread the blocks out and jumble the numbers around as in the picture below. Keep all of the numerals facing upwards. Then, set the challenge to build a tower putting the numbers in the correct order from 1-20.
If stuck on the number, count the dots!
I put Lego wheels on the base for my son since he loves trucks and cars, but any Lego base will do to help the tower from falling. He enjoyed driving his tower of 20 blocks around once he finished the task.
Differentiation option for older kids – Comparing and Ordering Larger Numbers
This activity can easily be adapted to suit older kids to work on comparing ordering larger numbers.
To do this, all I would do is label the blocks with the numbers appropriate to challenge the level of difficulty my students need.. Below is an example set for ordering 4-digit numbers.
Then set the challenge to build a tower in ‘ascending’ order (from least to greatest).
Another great activity that can be used at home or in the classroom is this fun Math Mystery below, which focuses on Comparing and Ordering numbers, 'Case of The Outback Outlaw'. Kids will be practicing this important skill whilst also working on solving who stole the opals from the Coober Pedy mine in the Outback of Australia.
It's available in four different levels to choose difficulty from. Click on the grade level version below to find out what number range/s are explored in each..
