EveryDay Math
Grade 5
Unit 1 - Number Theory
Lesson Objectives
1.1 - To acquaint students with the content and organization of the Math Journal and Student Reference Book. (Optional)
1.2 - To review rectangular arrays and the use of multiplication number models to represent such arrays.
1.3 - To provide a review of the meanings of factor and product; and to provide opportunities to factor numbers and develop automaticity with multiplication facts.
1.4 - To review divisibility concepts.
1.5 - To introduce divisibility rules for division by 2, 3, 5, 6, 9, and 10; and how to use a calculator to test for divisibility by a whole number.
1.6 - To introduce the classification of whole numbers as either prime or composite.
1.7 - To introduce square numbers and the exponent key on a calculator.
1.8 - To introduce the concept of square roots; and the use of the square-root key on a calculator.
1.9 - To review equivalency concepts for while numbers; and to introduce factor strings and prime factorization.
Note: Lessons are typically covered in one class period. Lessons 1.1 - 1.9 will be followed by a review lesson, and then a summative assessment of these skills. Formative assessments may be given throughout the lesson to help students gauge how well they are mastering the lessons, and when they need to seek out additional help from me. Students seeking additional support should sign up for that help during “Quiet Time.”
