Students will be able to solve multiplication problems with a multi-digit factors using partial products as a strategy.
Introduction
(5 minutes)
Write ‘Partial Product’ on the board and ask students, "What does this mean?"
Have students turn and talk to a partner to discuss its meaning. Remind students to think about similar words or math vocabulary they know.
Underline product and ask, "In math, what is a product?" Answers should include "the answer to a multiplication problem."
Underline part in the word partial, and prompt students, "If we know what the word part means, what might partial mean?" Answers might include that it's a piece of something; not the whole thing.
Explain that partial products are parts of an answer to a multiplication problem.
Tell students that today we are going to learn how to solve a multiplication problem by finding parts of the answer, or partial products.
