Monster Math Every year, I always like to review the different forms and ways to write a number. We use Everyday Math in our class and there are always questions about showing a number in many ways. While many of my students know how to show it using addition or subtraction problems, practicing the different forms like word, expanded, and using place value blocks are often forgotten, but still important. I am in love with Scrappin' Doodles monsters I use them for my grouping cards found HERE and was dying to incorporate them in a fun and engaging lesson.

Student sample in notebook. Write Numbers in Expanded Form is a good quick resource because I would have taken time to use the place value blocks in the manner she does to instruct.

Students sat on the floor and took notes as the video was shown on the SB. I noticed that she makes errors in reading her numbers by using the word "and". I was sure to point out that it is important to reserve 'and' for numbers with decimal points.

We then paused the video and re-read the numbers, using 'and' correctly. I pointed out that each number when written in expanded form needs to be thought about like the Slinky I asked them if this number had been "stretched out" completely.

They noticed right away that the thousands place had not been included. I asked a student to correct the mistake. We discussed if the zeros in the tens place were supposed to be there. I asked for a vote for those who thought it was important. Every student raised their hand.

I could see from this informal assessment that they were attentive to showing each place value in the equation. I talked about how the zeros in the tens place were not wrong, but generally, if there is a zero in a place value, we usually omit it.

This develops Math Practice Standard 7 as they strive to look for and make use of structure. They become aware of large digit numbers in the real world. I modeled the assignment by dropping down my classroom map of the United States.

I used the populations of cities, being sure not to go over one million.To write a number in expanded form, break apart a number, and write it as the sum of each place value. For example, = + + 20 + 4.

Decimals may also be expanded in a similar format: = + + Expanded form is a way to write a number such that all of the place value components of the number are separated. When we write a number in expanded form, each digit is broken out and multiplied by its place value, such that the sum of all of the values equals the original number.
