Students learn about comparing the size of numbers using the place value table. They use greater and less than symbols to compare the size of integer and decimal numbers. Less able students have access to a place value table and number line. More able students are taught to consider the upper and lower bounds for a range of decimals.
At the start of the lesson students recap finding the value of each digit using the place value table. In the development phase students use inequality symbols to make comparative statements about the size of numbers. At the end of the lesson they are challenged to create a range of numbers using select digits and the decimal point.
Differentiated Learning Objectives
- All students should be able to use < and > to compare the magnitude of integers from the place value table.
- Most students should be able to use inequality symbols to compare the magnitude of any positive number.
- Some students should be able to determine the upper and lower bounds for a range of numbers.
