Students will explore frequency tables, dot plots, and stem and leaf plots by creating different representations from a given set of data points.

Students will experience a hands-on lesson regarding ratios. While doing this, students will deepen their understanding of the concepts of ratios.

Students will work collaboratively with a partner to discover what is a line of symmetry.

Students use a pan balance model and manipulatives to identify a total that balances two parts. The use of the pan balance will help to develop the concept of equality. Students will develop the language of equality by reading and identifying the following expressions; balances, is the same as, is equal to, and equal before the symbol for equality is introduced. Students will identify an unknown part in a balance situation. Students will communicate ideas, explain, and justify how they solved problems.

The lesson requires students to match times to the nearest five-minute interval using an analog clock, digital clock, and time written in words. Students will sing a song, show and write the time to the nearest minute, and tell time using analog watches.

Students will perform an error analysis of common subtraction errors related to the standard algorithm.

Given one representation of a linear relationship, students will create a poster displaying the other three representations of linear relationships.

Students will learn how to use an input-output table using real-world examples.

Students will utilize manipulatives to create concrete and pictorial strip diagram representations in order to solve multi-step multiplication and division word problems.

Students will extend their knowledge of greater than and less than to numbers 80–120. Students will work in stations to deepen their understanding and have multiple experiences with the concept.

This lesson is a student discovery lesson that culminates in square root regression with technology. Students will use their study of inverses, the relationship between quadratic and square root functions, their previous knowledge of regression, and determine how to find the square root regression of real-world data.

This lesson will introduce fourth-grade students to the concept of a remainder and the meaning of a remainder in the context of a word problem.

Students will learn the concept of area by building a robot using manipulatives and transferring the representation onto grid paper. Then, students will determine the area of each designated body part on their think sheet.

This lesson is a 90-minute lesson that can be delivered in one block or split into two 45 minute lessons. The first part of the lesson engages students in a notice/wonder activity that is designed to help students begin to question how data is represented in box plots and dot plots. The second part of the lesson is designed for students to compare data in box plots and dot plots and identify truths and untruths about the representations.
