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) Source: Schmidt, M.E., (1995).
