Fifth graders build area models to represent multi-digit multiplication. This lesson is not complete, but having pupils learn first through hands-on experiences builds a solid mathematical foundation.

Students practice finding the sums of two-one digit numbers. In this addition lesson plan, students also record facts onto an addition chart.

Young scholars explore the additive identity property where they add multiple numbers to get to the number 6. In this number 6 lesson plan, students also work on their addition charts.

Students discover the urban ecosystem through a series of activities. They explore both the biotic and abiotic factors of the urban environment.

Students complete a unit of activities to learn about states of matter and how to measure matter. In this matter lesson, students complete 8 lessons to learn about matter, its states, and how to measure matter.

Students examine the functions of the different systems in the body. They discover how different systems must work together to make the body function correctly. They identify the needs of the body to help it survive.
