Parent & Child Activities

Calculus for Kids Activity Sparks
Natural Math has made these one-page activity guides for parents and kids to try activities that give insight into math concepts.

  • How You Slice It: Use your X-Ray vision on different patterns to see how a whole is made of different parts. From this viewpoint you can see how different building blocks lead to different outcomes. Is one slicing technique simpler than others? More fair? More predictable? More fun? Let’s find out.
  • Make Shapes with Sticks: Make models using integration, and learn to see flat 2D shapes as made from straight 1D lines. You can use craft sticks, matchsticks, toothpicks, or strips of paper to make your shapes. Can every shape be made from sticks? Are there hidden techniques to make complex shapes from simple lines?
  • What would a 3D Printer Do? Choose any object and ask: How would a 3D printer build it? How would it grow in nature? How would you make it with crafts? We can train our skills in thinking with analogies. In music, we can play the same song in different styles (rock, jazz, classical, rap). Calculus lets us “remix” an object by building it different ways.
  • Mosaics: 2D to 2D:  Let’s learn how to approximate curves with straight lines, and try to fill and measure complex shapes. You can use anything that is flat enough: craft foam, construction paper, sticky notes, tiles, fusible beads, or LEGO bricks. How can small pieces come together to show a larger image? Do grids help or hurt your project? Can you make a circle out of squares? Let’s find out.

Bedtime Math
From how many teeth there are in the world to how long it would take an army of ants to carry you across the country, this free website and app gives kids something fun and mathy to think and talk about with their families every night before bed. (Lots of printable games and activities, too!)

NEW! Games and Activities to Promote Early Math Learning
Parents can give pre-K children a boost in learning mathematics by noticing, exploring and talking about math during everyday activities at home or out and about. Discussing and exploring mathematics with children requires no special resources – here are 11 easy ways you can make math part of your everyday routine!

How to Make Tessellations
This easy guide for elementary school students teaches how to design your own tessellation patterns using paper, scissors, and tape. What can you create?

Make your own Snowflakes (PDF)
Snowflakes are fun decorations this time of year. Many people like to make their own and display them on doors and in windows to celebrate winter. Snowflakes are both delicate and beautiful. Each real snowflake is a uniquely fashioned ice crystal with a symmetry that reflects the symmetry of water molecules. This six-fold symmetry is shared by all snowflakes and is easy to replicate by folding paper. This template will let you make your own paper snowflakes to observe symmetry and share your creation.

Sesame Street Math is Everywhere
Look around: Exciting math opportunities abound! Sesame Street Math Is Everywhere aims to help parents, caregivers, and educators help young children explore and understand math in the everyday world by focusing on the broad thinking and reasoning skills required to master mathematics.

The Connectory
Spark your child’s curiosity: connect to a STEM opportunity for your child. The Connectory is a free portal that helps parents and other caregivers find local STEM education opportunities for kids in their lives.

Games & Puzzles

Games at PBS Kids
You can pair these online games with math activities for early childhood.

  • Animal Lost and Found: Help owners find their lost pets! Count eyes, ears and other body parts in this match game for preschool and kindergarten.
  • Building Sandcastles: Ready to play in the sand and practicing learning shapes for preschoolers and kindergartners? Match the shapes of wet sand with their outlines to build different sandcastles.
  • Let’s Tessellate: Choose a shape and a color and then tessellate! See your shape repeat again and again to make a beautiful pattern in this fun tessellation math game.
  • Pattern Matcher: In these fun pattern games for kindergarten and preschool, silly pictures make patterns that repeat. Can you find the patterns that repeat the same way?
  • Time to Move: Help move these fish to their new homes with this measurement game for kids! Which fish move where? Catch and measure each fish to find out.

Gracie and Friends Early Math Apps
2017 Festival presenter First 8 Studios™ at WGBH creates free Gracie and Friends series of mobile apps with titles like Birthday CaféLemonade Stand, and Jungle Gym. Kids can explore games that teach two key concepts for early math learning: subitizing (learning to “see how many” objects without counting each one), and equipartitioning (learning how to divide objects into equal pieces).

ThinkFun Games
National Math Festival program collaborator ThinkFun specializes in games that offer both fun and STEM development to engage kids and families in learning 21st century thinking skills and solving puzzles. Check out these games that were a hit with visitors at the 2017 Festival!

  • Rush Hour: In Rush Hour, a sliding block logic game, you have to battle the gridlock as you slide the blocking vehicles out of the way for the red car to exit. This perennial favorite board game is also available to play for free online or as a mobile app.
  • Chocolate Fix: This deductive logic game for ages 8+ gives clues that will help you to fill the tray with all nine chocolate pieces in their correct positions. Similar to Sudoku, you must examine all clues on the challenge card before making a move. You can also play online for free.
  • Balance Beans: This bean-filled logic game is a fun way to introduce young learners to elementary algebra, via a game of card-based challenges using beans balanced on a seesaw. When you balance the Seesaw, you are actually balancing an equation! As the challenges get harder, you’ll rely less on trial and error – and more on math and reasoning skills.
  • ShapeOmetry: ShapeOmetry aims to develop spatial, abstract and quantitative reasoning skills. To solve the puzzle challenges, stack green pieces on top of blue pieces, or vice versa, to create identical shapes. Through hands-on play, players build key skills, strategies and mathematical understandings, such as part-to-whole relationships.
  • Math DiceMath Dice Jr. and Math Dice are an easy-to-learn, skill based game where players use dice rolls to form math equations to get as close to a target number as possible. It can be played competitively or cooperatively, as well as online!
