The lesson appeared in Carrie De Francisco and Marilyn Burns’s Teaching Arithmetic: Lessons for Decimals and Percents, Grades 5–6 (Math Solutions Publications, 2002). I asked the students, “According to a grocery’s digital scale, a lobster weighs more than two and fifty-six–hundredths pounds but less than two and fifty-seven. Lesson 1: Adding and Subtracting Using Mental Math Lesson 2: Estimating Sums and Differences Lesson 3: Adding Whole Numbers Lesson 4: Solve Two-Step Problems Lesson 5: Communicate About a Choice of Calculation Method Lesson 6: Adding Decimals. With 27 different centers, you are sure to have enough materials to get your students rockin’ and rollin’ with their numbers to 30. Students practice various kindergarten math standards. This student is counting and completing a color by number. Another skill is counting and comparing numbers. Our math lessons are designed to make math meaningful to the student. Each math lesson provides in-depth instruction ideal for learners of all ages and abilities. Read the terms and conditions for using our sample lessons below.
