Second graders listen to the story Miss Nelson is Missing by Harry Allard and James Marshall. In this literature lesson, 2nd graders predict the story's ending with drawings and discussions within groups.

Students use video integration to help them learn about non-standard measurements. In this measurements lesson, students watch a video about measurement. Students determine which non-standard measurement unit would be best to solve the...

Learners study the measurement formulas for area and perimeter in real-life situations. In this area and perimeter lesson, students design a bed and arrange furniture in a hotel room using area and perimeter formulas for a 7 1/2 foot...

Students measure their own silhouette using Unifix cubes. They measure a drawing using non-standard measurement. They swap drawings and compare their measurements.

How do you fit a tape measure around the Earth? No need if you know a little geometry! Pupils begin by extending their understanding of the Side Splitter Theorem to a transversal cut by parallel lines. Once they identify the...

Inscribed angles are central to the lesson. Young mathematicians build upon concepts learned in the previous lesson and formalize the Inscribed Angle Theorem relating inscribed and central angles. The lesson then guides learners to prove...

Individuals measure a computer monitor and determine how accurate their measures are. The eighth segment in a series of 20 introduces the concept of percent error. Pupils find the percent error of their measurements and discuss the...

Concepts are only valuable if they are applicable. An informative resource uses concepts developed in lessons 26 and 27 in a 36-part series. Scholars write equations and solve for missing side lengths for given right triangles....

Explore angle relationships created by parallel lines and transversals. The 13th lesson of 18 prompts scholars use transparency paper to discover angle relationships related to transversals. Learners find out that these angles pairs are...

Fractions can be tricky. Why not have kids think of fractions like they think of eighth, quarter, and half notes? In teams, the class creates four-measure patterns with their percussion instruments. They need to explain their rhythm...

Can you use triangles to create a circle? Learners develop the unit circle using right triangle trigonometry. They then use the unit circle to evaluate common sine and cosine values.

Maximizing resources is essential to productivity. Class members complete an activity to show how math can help in the process. Using a piece of construction paper, learners construct a box with the maximum volume. Ultimately, they...

Help pupils to determine whether using square roots is the method of choice when solving quadratic equations by presenting a lesson that begins with a dropped object example and asks for a solution. This introduction to solving by...

What does it take to show two triangles are similar? The 11th segment in a series of 16 introduces the AA Criterion for Similarity. A discussion provides an informal proof of the theorem. Exercises and problems require scholars to apply...

Use a West African folktale to practice several different skills in your first grade classroom. Learners read The Clever Monkey Rides Again and focus on rhyming words, reading comprehension, measurement, art, movement, and word...

What's the moral of this story? Units save lives! Teach measurement conversion through storytelling in a quick math-based lesson. Young scientists learn how one country's decision to swap from imperial to metric standard units caused an...

Lead the class in a Greek history lesson with a geometric twist. Pupils relate a short video about geometric properties to modern-day methods of solving for unknown angles. They discuss parallel line theorems and complete...

Provide your emerging mathematicians with the tools to learn as they incorporate auxiliary lines to solve unknown angle proofs in this continuing segment. They decipher information from a diagram to uncover the missing pieces and...

Is that drawn to scale? Capture the artistry of geometry using the ratio method to create dilations. Mathematicians use a center and ratio to create a scaled drawing. They then use a ruler and protractor to verify measurements. 

Define terminology related to a circle. Practice accuracy in measuring and then create a spreadsheet based on data collected from solving for parts of a circle. Groups can have fun analyzing their data as it relates to Pi.

Upper graders explore the topic of volume. In this math lesson plan, pupils count volume in cubic units, multiply to find volume, estimate volume, write a multiplication sentence to find the volume, and make a cost analysis of different...

Gain practice converting between metric units of volume and mass. The class goes over the procedures for making the conversions as a whole. The strategy used here includes making charts that show the relationships between the...

Investigate the length of various objects in metrics! In this measurement lesson, 2nd graders estimate and find the length of objects in the classroom using centimeters.

You've investigated relationships between chords, radii, and diameters—now it's time for arcs. Learners investigate relationships between arcs and chords. Learners then prove that congruent chords have congruent arcs, congruent arcs have...
