Comparing Lines and Linear Equations
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...

Translating Between Repeating Decimals and Fractions
Model for your young mathematicians the process for converting repeating decimals to fractions. To demonstrate their understanding of the process, class members then complete and assessment task and participate in an activity matching...

Multiplying Cells
Powers of two: it's a matter of doubling. A short summative assessment task asks pupils to determine a process to calculate the number of cells at given time intervals. They use powers of two in order to calculate the number of...

Classifying Equations of Parallel and Perpendicular Lines
Parallel parking might be difficult, but finding parallel lines is fairly simple. In this lesson, learners first complete an assessment task involving parallel and perpendicular lines in the coordinate plane. Individuals then take part...

Stick Patterns
Sticks and stones may break my bones, but these sticks will make me smarter. Pupils examine arrays of sticks to determine the next array in a pattern. They use the number of sticks added to each previous array to determine a recursive...

Did I Trap the Median?
One of the key questions in statistics is whether the results are good enough. Use an activity to help pupils understand the importance of sample size and the effect it has on variability. Groups collect their own sample data and compare...

Scatter Graphs
Make an estimate by getting in line. The class works with scatter plots and lines of best fit to make an estimate for given values. Pupils determine whether there is a positive or negative correlation and draw a best-fit line. Using the...

Area and Circumference of Circles
Don't go around and around, help your class determine amounts around and in a circle with a video that connects circumference to the perimeter or the distance around an object. The resource includes 14 questions dealing with circles and...

Rotation
Two videos show first how to perform a rotation, given the center, the angle, and the direction of rotations. Individuals then see how to find what the rotation is from one figure to another. Pupils practice doing both in seven problems...

Reflections
Tracing paper is not just for art anymore — pupils can use it to find reflected images, too! Two videos show how to reflect images using tracing paper and find the reflection between the pre-image and image. Learners perform reflections...

Translations
Introduce translations as transformations that move figures in horizontal and vertical distances with a video that shows how to translate the figures. A second video covers how to determine the translation that has occurred. Pupils...

What is Time?
Does it ever seem like time is slipping through your fingers? Model the passing of time with an hourglass activity in which individuals determine whether hourglasses are the most efficient way to measure time.

Bubble Trouble!
Which fluids make the best bubbles? Pupils experiment with multiple fluids to determine which allows for the largest bubbles before popping. They gather data, analyze it in multiple ways, and answer analysis questions proving they...

Factory Functions
Solve a real-life problem using function-building skills. Presented with an open-ended question, scholars complete a checklist to create and justify a solution in an interesting algebra project. The checklist asks for justifications of...

Polygon Polynomials
Patterns in polygons lead to patterns in polynomials. Presented with a series of polygons, individuals create polynomial expressions to represent their patterns. The algebra project consists of nine problems that incorporate polynomial...

Concepts Of Division
In a comprehensive and well-outlined series of activities, the class investigates how division is the same as repeated subtraction. During guided practice, they take notes on turning sample word problems into solvable equations and...

Use Estimation to Compare Numbers
"Take a walk" with this activity and estimate how many birds, ants, turtles, flowers and children getting on a bus that you see. Based on the size of a single set of 10 objects, learners estimate how many are in the whole group. They...

Count the Dots: 10 Plus More Makes 11-20
Young math learners count and circle a group of 10 dots. They count on the extras, and write the corresponding number between 11 and 20 in a box. Nine practice problems in all.

Gifts from Grandma, Variation 1
Composed of three word problems, this math activity exposes young mathematicians to relationships present in multiplication and division. The first problem is most useful with a tape diagram in which learners are working with equal-sized...

Justifying Answers
Young scholars study story problems and learn how to find and justify their answers. They will use a story problem and then respond to the prompt questions from the teacher. They must add and subtract facts to 6 and learn how to justify...

three Names Lesson
After the book Three Names is read aloud, math vocabulary is introduced . Either alone or in groups, learners use the vocabulary words in a meaningful sentence. Then they complete the provided worksheet.

Domain: Operations and Algebraic Thinking
Practice basic operations for young mathematicians in fun ways! Using two decks of cards (Ace through 10 plus the joker), learners play "memory" by matching numbers that can be added to make 10 and writing number sentences. In another...
