It's all relatively simple once you get the gist. Young mathematicians learn about sample spaces and simple probability by conducting an activity with dice. To complete the second of six parts in the Statistics and Probability unit, they...

Of course, there might be a correlation! Young mathematicians investigate several different data sets, create scatter plots, and determine any correlation. They consider whether a causation exists between any of the variables in question.

Pack the lesson into your plans. Young mathematicians learn about packing and optimization with the context of circular paving stones. They use coins to model the paving stones, and then apply knowledge of circles and polygons to...

Bridge young mathematicians' knowledge of engineering and design. Pupils use two desks and a plastic sheet to simulate a bridge. After learning about energy transformations, they use available materials to design a sensor that detects...

Patterns and polynomials go hand in hand. Budding mathematicians analyze sequences of dot diagrams to discover the patterns in the number of white dots and black dots. They use the identified patterns to write and simplify a polynomial...

A lesson asks young mathematicians to investigate the social determinants and the environmental factors that influence risk factors associated with the spread of COVID-19. Class members then brainstorm what they can do to alleviate the...

How vulnerable are you to COVID-19? High school mathematicians use the Pandemic Vulnerability Index to create models that help them collect and analyze data about the risk factors associated with COVID-19. After investigating four groups...

There are plenty of fish in the sea, but only a few good resources on regression. Young mathematicians first perform a linear regression analysis on provided weight and length data for fish. After determining that a linear model is not...

Reinforce multiplication strategies with a lesson that examines a word problem and the distributive property. Mathematicians work collaboratively to solve the problem, create a poster with their solution, and share their preferred method...

"What are fractions composed of?" is the essential question of a lesson designed to enhance understanding and strengthen the foundation of adding fractions. Mathematicians start by discussing what makes an equation true or false,...

Following a catchy video about decomposing numbers, young mathematicians build and write numbers using dice. Class members work to create an anchor chart that displays six ways to make numbers. Beans get scooped and estimated, then...

The story, How Many Jelly Beans? by Andrea Menotti introduces a lesson about partial quotients. Mathematicians practice rounding and multiplying, then work in small groups to connect those skills with division and partial...

Following an engaging video, mathematicians solve a word problem about baking cupcakes using fractions. Scholars practice different problem-solving strategies, then find different ingredient amounts for their recipes. Pupils solve a...

A lesson on percents, perchance? Young mathematicians learn about the meaning of percents. They play a game using dice to write and solve questions involving percents.

If you made a doll version of yourself, how tall would you be? By using ratios and proportions, young mathematicians are able to answer this question. They actually create their dolls using clay, paper, or other materials.

Can you make money from math? Young mathematicians match real-world applications to systems of linear equations. In groups, they investigate investment strategies by writing systems of linear equations which helps them determine which...
