Comparison is one of the most crucial math skills second graders learn, because it can be applied to so many other disciplines across the elementary school curriculum. In this measurement and data lesson, kids will work on object comparison and graphing. The exercises ask kids to list objects in size order, estimate length, note differences in length, and make bar graphs.

Sorting and classifying is a key math skill for preschoolers to master before moving on to higher-level concepts. This guided lesson teaches kids to sort objects and identify what doesn't belong. Each exercise aims to engage preschoolers in order to build a positive relationship to learning and make early math a joyful occasion. When finished with the lesson, check out our sorting and classifying worksheets.

Calculating the volume of rectangular prisms is a new skill that is introduced in 5th grade. Students will apply mathematical formulas to find the volume of different kinds of figures and also determine the volume of a figure composed of two connected rectangular prisms. Learners will also work with other kinds of measurement when they make larger or smaller versions of figures (to scale) and learn to convert measurements.

The ability to compare numbers with ease is crucial to understanding the relationship between numbers, also called number sense. The abstract nature of number sense makes extra practice crucial. This guided lesson helps kindergarteners to learn this skill with targeted instruction and engaging exercises. Further opportunities for practice can be found in the comparing numbers worksheets suggested to go along with this lesson.

Representing data on graphs makes math visual and involves some creativity and design. Plotting data using fractional units takes their learning one step further. Also in this unit, students learn to measure using both traditional units (like inches, feet and yards) and metric units, and how to convert measurements within each system. The concept of measurement gets two dimensional when students explore measuring and working with angles.
