This lesson is designed to help students understand factors of whole numbers. - Finding Factors

This lesson plan's activities give students practice in finding the factors of whole numbers. - Sets and the Venn Diagram

This lesson is designed to help students understand the ideas surrounding sets and Venn diagrams.

- IXL Game: Mixed operations: Addition, subtraction, multiplication, and division word problems

This game helps fourth graders understand how to read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. This is just one of many online games that supports the Utah Math core. Note: The IXL site requires subscription for unlimited use.

- Arithmetic Four

In this game for two players, students solve problems involving whole number and integer addition, subtraction, multiplication, and division. - Order of Operations Four

This applet pits two players against each other in solving expressions using the four basic operations.

- Comparing Fractions with Lines

This lesson will help students simplify fractions, compare and order them on a number line, and estimate their value. - Equivalent Fractions Finder

Students doing this lesson will visually experiment with the relationship between the value of fractions and areas within a square or a circle. In doing so they will practice simplifying fractions and compare fractions.

- Comparing Fractions with Lines

This lesson will help students simplify fractions, compare and order them on a number line, and estimate their value. - Comparing Two Different Pizzas

Students are given the example of two whole pizzas, one large and one medium. They must determine what fraction of the two pizzas has been eaten if someone eats 2 slices of the medium pizza. They must explain their reasoning and draw a picture to illustrate their solution. - Histograms and Bar Graphs

This lesson will introduce students to histograms and bar graphs and help them understand the difference between them. - Making 22 Seventeenths in Different Ways

This is a straightforward task related to adding fractions with the same denominator. The main purpose is to emphasize that there are many ways to decompose a fraction as a sum of fractions, similar to decompositions of whole numbers that students should have seen in earlier grades. It is suitable for assessment or, with opportunity for classroom discussion, it could also be useful in instruction. - Multiply Fractions Jeopardy

This game can be played by one or two players as they solve multiplication problems with fractions. - Peaches

This task provides a context where it is appropriate for students to subtract fractions with a common denominator; it could be used for either assessment or instructional purposes. - Plastic Building Blocks

The purpose of this task is to have students add mixed numbers with like denominators when given a problem in the context of two students building a castle out of building blocks. - Single Fraction Finder

In this lesson students will practice dividing a whole into a fraction and visualize fractions on a number line. - Subtraction of Fractions Using a Visual Model

Students will learn how to subtract fractions with unlike denominators by using a visual model. NOTE: You have to create a Free PBS Account to view this web page, but it is easy to do and worth the effort. - What Fraction of this Shape is Red?

This Teaching Channel video shows how students can explore part and whole by creating pattern block designs. (4 minutes) - Writing a Mixed Number as an Equivalent Fraction

This task relates to writing a mixed number as an equivalent fraction. The purpose of this task is to help students understand and articulate the reasons for the steps in the usual algorithm for converting a mixed number into an equivalent fraction,

- Adding Tenths and Hundredths

This problem simply asks students to add the tenths and hundredths together. - Fraction Conversion 2 (with percents)

When completing this lesson students will understand how to convert fractions, decimals, and percentages. - How Many Tenths and Hundredths?

In this task students are given a list of equations such as "1 tenth + 4 hundredths = ______________ hundredths" and asked to finish the equations to make true statements.

- IXL Game: Measurement: Convert mixed customary units

This game helps fourth graders understand relative sizes of measurement units within one system of units. This is just one of many online games that supports the Utah Math core. Note: The IXL site requires subscription for unlimited use. - Smile Metric Style

In this activity students work with the metric system by measuring each other's smiles. - The Iditarod & Math

This Teaching Channel video and lesson plan will help students calculate elapsed time and distance using real-time data. (7 minutes) - What Does it Mean to Measure?

This lesson plan asks students to measure properties of various objects including weight, area, and volume and determine the appropriate metric unit for taking the measurements.

- Area (elementary)

In this lesson students will find the area of rectangular shapes and irregular shapes with right angles.

- Angles (elementary)

This lesson is designed to help students learn about classifying angles by their measure.

- An Introduction To Quadrilaterals

In this lesson the student is introduced to parallelograms, rectangles, and trapezoids and practices creating various types of quadrilaterals. - Angles (elementary)

This lesson is designed to help students learn about classifying angles by their measure. - Area Explorations

In this lesson, students will explore the area of irregular shapes to find multiple different methods for calculating area - Floor Tiles

This lesson will help students identify and examine symmetry in geometric figures as well as describe and classify polygons. - IXL Game: Geometry: Parallel, perpendicular, intersecting

This game helps fourth graders draw points, lines, line segments, rays, angles, and perpendicular and parallel lines. This is just one of many online games that supports the Utah Math core. Note: The IXL site requires subscription for unlimited use. - Sets and The Venn Diagram (Beginner)

By introducing students to the idea of a set, this lesson will help students learn about the vocabulary of sets and Venn diagrams, as well as how to arrange things in a Venn diagram. - Tessellate!

This lesson and activity will help the student understand how to classify two-dimensional figures based on properties. The student manipulates shapes to create now polygons.
