Lesson Plan List for: Operations

Change grade range

Resource	Grade Level	Media Type
Creating Equal Shares Students practice fractions by sharing certain numbers of objects among different numbers of people. They begin with unit fractions and move to sharing multiple objects among multiple people, in which a < b, and to produce fractions less than one.	3-6	Lesson Plan
Estimation Students practice their estimation skills by estimating time and numbers of objects in situations in which counting is not feasible or necessary.	3-6	Lesson Plan
Filmmaking on a Budget Students practice column addition in relation to budgets and are asked to create budgets that meet particular totals.	3-5	Lesson Plan
Introduction to Negative Numbers Students are introduced to the concept of negative numbers through simple equations and the use of a number line that is extended beyond zero in the negative (left) direction.	4-8	Lesson Plan
Inverses as a Form of Undoing Students learn about inverse operations and how to write the inverse of a sequence of operations. They practice by solving two-step equations and checking their solutions.	5-8	Lesson Plan
Multiplication as Combinations Students learn to systematically identify all possible combinations, first among 2 objects with 3 possibilities each and then among 3 objects with 2, 2 and 4 possibilities each.	3-6	Lesson Plan
Multiplication as Replication Students build tables and use patterns as an introduction to multiplication. They are encouraged to use multiplication by 10 or 100 for larger values as the beginnings of commutativity and distribution are introduced.	2-5	Lesson Plan
Multiplication by 10 Students practice multiplying by 10 by adjusting a recipe to be 10 times larger. They examine the results to learn the procedure of adding a 0 to the multiplicand when multiplying by 10. They also practice dividing by 10 in the same manner.	3-6	Lesson Plan
Planning a Budget Students practice column addition and lining up decimal points in the context of money while they watch a video segment. Assessments provide more practice adding numbers in columns, and students troubleshoot an error in misaligned decimal addition.	3-5	Lesson Plan
Sharing As a Model for Division Students use manipulatives to share objects among different sized groups and practice dealing rounds as a division method. They learn to apply the method to problems using numbers and how to write these problems as multiplication and division facts.	3-5	Lesson Plan
Strategies for Dividing Numerically Students practice division and the concept of breaking a total into parts that are smaller and more easily divided.	3-5	Lesson Plan
Summing Integers:Positive and Negative Students add, subtract and compare positive and negative integers.	4-8	Lesson Plan
Using Combinations to Solve a Puzzle Students solve puzzles by eliminating possible solutions using clues. Assessments test whether students can predict the number of combinations needed to solve similar puzzles.	2-5	Lesson Plan
