Subject Area:
Math Place Values
Strategy: Place Value Concepts
Appropriate Grade Level:
Elementary 1– 4 Grade
Procedures/Steps:
The student is asked to demonstrate their understanding of a three digit number by using blocks.
1.
Provide the student with bocks that represent 1’s, 5’s, 10’s, and 100’s
2.
Give the student a specific number
3.
Have the student use the blocks to represent this number
4.
Now, have the student use a different combination of these blocks to represent the same number.
5.
Ask the following questions depending on the students’ goals, or lesson objectives:
•
“Can you think of another way to show the number ___?”
•
“How many different ways are there to represent ___ using only these blocks?”
•
“What would the number be if we added____ number or blocks?”
•
“What would the number be if we took away _____ number of blocks?”
For example: The blocks to the below represent the value of 24. Hundred’s Value
Thousands Value
One’s Value Ten’s Value
Comments and/or tips:
Pre-assess your student to be sure that pre-requisite math and counting skills exists.
For instance, the student must understand the concept of “value places.”
An example of a challenge question for step 5 would be:
•
“What number would be _(2)_ 100’s blocks, _(3)_ 10’s blocks, & _(1)_ 1’s blocks represent?” (Student would respond: 231)
