Drawing circles isn't the only thing compasses are good for. In this first installment of a 36-part series, high schoolers learn how to draw equilateral triangles by investigating real-world situations, such as finding the location of a...

It's the parts that make the whole. Learners apply volume formulas to composite figures to find the total volume of the figure. Previous lessons in this series taught the methods for finding the volume and/or dimensions of...

Communication is key. Eight sample items show how important communication and reasoning is for sixth grade mathematics. Part of the Claim 2-4 slide show series, the presentation uses concepts from fifth and sixth grade to illicit...

Calculate the areas of scale drawings until a more efficient method emerges. Pupils find the relationship between the scale factor of a scale drawing and the scale of the areas. They determine the scale of the areas is the square of the...

Good graphs make solving systems simpler. Pupils answer 18 questions shown in a PowerPoint presentation as part of the Claim 1 Item Slide Show series. By considering these questions, they review the concepts of graphing equations and...

What is an annulus? Pupils first learn about how to create an annulus, then consider how to find the area of such shapes. They then complete a problem set on arc length and areas of sectors.

We know that sample data varies — it's time to quantify that variability! After calculating a sample mean, pupils calculate the margin of error. They repeat the process with a greater number of sample means and compare the results.

Scholars first complete an assessment task on writing linear equations to model and solve a problem on a running race. They then take part in a card matching activity where they match equations and graphs of lines to diagrams of fluid...

Make sure your learners' understanding of fractions is on-point using this series of skills practice worksheets. Covering a variety of topics from basic place value and fraction/decimal conversion, to performing all four operations...

Fifth graders make the connections using models between multiplying a fraction times a whole number and multiplying a fraction times a fraction. After completing three teacher-led activities, pupils access a website on their own to play...

You'll need scissors, glue sticks, and mini whiteboards for this activity on rational and irrational numbers. Learners work in groups to classify a variety of expressions as rational or irrational. They are also given a mock discussion...

Young mathematicians work through the concept of converting a shaded ten-frame into a mixed number and a decimal. Learners must first identify the number of wholes. Then, they find the fraction part. After writing the...

Using a Smart Board, or a plain ol' white board or chalkboard, the teacher pulls up a grid and demonstrates how squares and rectangles can be divided up into equal parts. The class will get their own graph paper to draw shapes and divide...

Visual models support young mathematicians as they deepen their fractional number sense in this elementary math lesson plan. Using fraction circle manipulatives, children explore basic unit fractions as they develop the...

Adding and subtracting mixed numbers will be a breeze with this guided instructional activity packet. Learners work through examples outlining each step including rewriting mixed numbers as improper fractions, adding numerators, and...

Do ratios have values? The seventh lesson in a series of 29 introduces the value of a ratio. Pupils create associated ratios to a given ratio. They also describe the fraction associated to the ratio as the value of the ratio.

Warm-up pupils' fraction muscles with a four-question quiz, then delve into a learning game designed to reinforce the concept of simplifying fractions. Based on the "I do, We do, You do" method of teaching, the lesson directly...

Reinforce concepts and encourage learner engagement with a collection of math games, science experiments, and cross curricular activities. In one fun resource, learners sort objects, keep a diary of everyday fractions, play a game using...

What can math say about natural phenomena? The fifth STEM lesson in this project-based learning series asks collaborative groups to choose a phenomenon of interest and design an experiment to simulate the phenomenon. After collecting...

There are many ways to correlate coffee to life, but in this case a worksheet looks at the price of two different sizes of coffee. It requires interpreting a graph with two unknown variables, in this case the price, and solving for...

How many days will it take Louis to save enough money for school supplies and new pair of shoes? Focus on Common Core math standards with a two-part task that involves a word problem and counting manipulatives.

Test your scholars' knowledge of a multitude of concepts with an assessment aligned to the California math standards. Using the exam, class members show what they know about the four operations, positive and negative numbers, statistics...

How much does your class know about Puerto RIco? How much can they learn from the back of a 2009 quarter? Use the coin, part of a series of quarters that depict US territories, to teach learners about the geography, culture, and history...

In this fractional parts worksheet, students use division and multiplication to help them find the fractional parts of a number for the thirty questions. Students then answer two test prep word problems.
