:

###### Supporting targets:

###### 1:

Compare numerals to determine more, less, or equal.

###### 2:

Use place-value understandings to help determine if numbers are more, less, or equal.

###### 3:

Use manipulatives to determine more, less, or equal by equating quantity to length (i.e. Which is bigger 20 or 32? Line up 20 blocks end-to-end and 32 blocks end-to-end. Which is longer?).

###### Grade:

1st

###### Vocabulary:

More, Less, Equal (=), Greater than (>), Less than (<), Compare

Activities:

Students

- compared 2 two-digit numbers
- wrote the appropriate symbols (>, <, =) to show which number was more, less, or equal
- used base-ten blocks to help explain how they determined which was more, less, or equal
- found the greatest and least numbers in a set of numbers

### Home Exploration

Ms. Brianne believes that 23 is greater than 32. Do you agree with Ms. Brianne? Prove your answer.

None

Remind them to think about place value and how many tens and ones are in each number. Students can draw pictures to help them explain their reasoning.

I disagree with Ms. Brianne. 32 is bigger because there are 3 tens (30). 23 only has 2 tens (20) which is less than 3 tens (30).
