Students will be able to divide decimals by whole numbers.
The adjustment to the whole group lesson is a modification to differentiate for children who are English learners.
Tell students that today they will be learning how to divide decimals by whole numbers.
Ask students to think of a time when they would need to divide a decimal by a whole number. Take several examples. If students are having trouble thinking of an example, remind them that money is represented as a decimal.
Give students an example. Example: You and your two friends ran a lemonade stand. You made $63.12. How much money would each person get?
Write out this word problem as an expression and use the standard algorithm for division. Show students that the divisor, or the number to be divided by, would be three and the dividend, or the number being divided, would be $63.12.
Allow students to use their home language (L1) or new language (L2) in their discussions.
Tell them to restate the math problem you provide without using numbers.
Have students tell you the numbers that represent both the divisor and the dividend after you reveal the answer.
Write the academic language they can use throughout the lesson on the board as you introduce the language.
Ask students to share the operation they think would apply to the math problem and how they know they're right (e.g., "I need to divide to solve this problem because ________. I know this is right because ________.").
Tell them to restate the meaning of "dividend" and "divisor."
