Students use rounding and compensating with whole numbers and explain how to use the empty number line to show additions and subtractions. They round and compensate in relation to decimal subtraction Background

Students use comparisons, graphing, patterning, and sorting, and develop language skills as they explore the five senses.

Fifth graders practice using estimation. In this estimation lesson, 5th graders add, subtract, multiple, and divide using whole numbers, fractions, and decimals. Students decide upon instances when estimation is more appropriate than...

Students investigate how to denature proteins. For this denaturing protein lesson plan, students explore the different ways to denature proteins in the lab. They use heat, acids and bases, organic compounds and heavy metals to denature...

Students conduct an experiment. In this water lesson, students watch the lesson "Float and Sink" on an interactive website. Students learn how to test items in water and then work in groups to test their items. Students discuss their...

Students induce an electrical charge on various objects, and experiment with electrical repulsion and attraction. They define related vocabulary, play Bingo and complete a take-home quiz.

Students research tornadoes. For this weather lesson, students construct a KWL chart on tornadoes and view the video National Geographic-Tornadoes. Students discuss the facts they learned from the film and complete the KWL chart.

Students explore the water cycle. In this earth science lesson plan, they read the book Water Dance by Thomas Locker and use an interactive whiteboard to review the water cycle with an interactive website.

Students examine bone fractures and the role that engineers play in repairing them.  In this biomedical engineering lesson students describe the factors that engineers consider when designing devices. 

Students research volcanoes. In this volcanoes instructional activity, students visit websites with worksheets about the terms for volcanoes and volcanic eruptions in the world. Students complete the work online and play a game for...

Young scholars work together to review what they know about damage during tornadoes. They design a structure that they hope protects people against tornadoes. They share their structure with the class.

This resource provides information about commutative and associative properties of addition.

In this lesson on the associative property of multiplication, students explore grouping factors, learn key vocabulary, and apply their learning to a real-life scenario.

This resource provides information about the commutative and associative properties of multiplication.

An introduction to the associative property of multiplication. Includes examples and practice problems throughout, along with explanations of solutions.

A detailed example is used to demonstrate the difference between the commutative and associative properties of addition.

Generate equivalent expressions using two additive properties. This video focuses on using the associative and commutative properties of addition to combine like terms, simplify expressions, and create equivalent expressions.

In this exercise, students practice using the associative property of multiplication. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.

Practice changing the grouping of factors in multiplication problems and see how it affects the product. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Sixth graders will create a properties foldable as a study tool.

Reviews what the associative property of multiplication is and presents several practice questions along with explanations of their solutions.

In this lesson on adding and subtracting, young scholars will learn to idenitfy and apply the commutative and associative properties of addition while utilizing their knowledge of fact families to correctly solve problems.

Children need to understand why the mathematical properties work and how they are applied. In this activity, we explore modeling and "proving" the associative property.

This is a great place to gather ideas for introducing and developing the multiplication properties concepts for commutative, associative, identity, and zero properties. Materials, preparation, prerequisite skills and discourse are all...
