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.
This video allows me the opportunity to instruct and stop when I need to to bring out certain points, answer questions and then monitor student notes and progress.
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.
I told them it was a common mistake, however, to leave two numbers together accidentally and that they needed to be extra careful to be sure each place value was separated. More Practice and Homework 15 minutes To help boost students' number sense and help them apply their understanding and connection to the real world, I looked for texts that displayed large numbers that would be connected to something interesting.
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.
Module 1: Digits, Place Value, and Reading and Writing Numbers heartoftexashop.com Page 7 Now we will look at how to write a number using digits given a word statement. Using Place Value to Write Numbers (Number and Algebra: Module 5) For teachers of Primary and Secondary Mathematics Cover .
heartoftexashop.comA Generalize place value understanding for multi-digit whole numbers. heartoftexashop.com1 Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place .
Place-value notation is a system of numeration where the value of a numeral symbol (a digit) depends on its position within the numeral string: a digit in a higher position is a multiple of a higher power of the base, while a digit in a lower position is a multiple of a lower power of a base; these multiples are then added up to give the value of the number.
