Students will be able to compare two-digit numbers, using the symbols for greater than, less than, and equal to.
The adjustment to the whole group lesson is a modification to differentiate for children who are English learners.
To begin the lesson, tell the class that they will be practicing comparing numbers.
Ask for a student volunteer to define the word compare. After some discussion, remind your class that compare means to see if one number is the same as, smaller than, or bigger than another number.
Write the terms greater than, less than, and equal to on the whiteboard.
Prompt your class to tell you what each of these terms mean. After some students share what they believe each means, write the definition for each on the board. Remind the class that greater than means bigger, less than means smaller, equal to means the same.
Explain that as a class, everyone will review the symbols used to compare numbers.
Define symbols as things that are used to stand for or represent something. In this case, symbols are used to compare numbers by size.
Gesture with your arms wide as you say in a loud voice, "greater than", arms close together as you say in a whisper voice, "less than," and hold arms parallel to form an equal sign as you say, "equal to."
Instruct students to define the vocabulary in their home language (L1).
Build understanding of symbols by asking students to name different symbols, such as a dollar sign or a smiley face. List suggested symbols and their meanings on the board.
Create an anchor chart of previously studied math symbols, such as the plus and minus sign. Include the symbol, name, and meaning. Add the greater than, less than, and equal to symbols to the chart for reference.
