Monster Math Measurement Activities for Kids: Problem Solving with Yarn, Straws, Paper Clips and Number Cards

Need a hands-on math activity that feels more like a scavenger hunt than a worksheet? This Monster Math measurement activity gives kids ten playful ways to practice problem solving, number recognition, comparison, ordering, and early measurement skills using simple supplies you probably already have at home.

This is the kind of math I love most: the sneaky kind. Kids are counting chairs, comparing hair length, measuring with paper clips, testing container capacity, and hunting for numbers without realizing they are building real math vocabulary and reasoning skills.

Translation? It is math with a monster-sized dose of “Wait, can we do one more?” energy.

What Is Monster Math?

Monster Math is a hands-on math box you can build over time with simple household supplies, printable cards, small manipulatives, and open-ended activities. Think of it as a little math toolkit kids can pull out for counting, sorting, comparing, measuring, building, and problem solving.

This activity is part of the Monster Math series and continues the problem-solving practice from Monster Math Tangram Problem Solving. It also introduces early measurement concepts using nonstandard units before kids move into rulers, yardsticks, and standard measurement tools.

Why Kids Should Measure with Yarn, Straws and Paper Clips First

Before kids fully understand inches, feet, centimeters, rulers, and yardsticks, they need lots of real-world experiences comparing objects directly. That means asking questions like:

• Which one is longer?
• Which one is shorter?
• Which container holds more?
• How many paper clips long is the book?
• Can we put these in order from smallest to tallest?

Using nonstandard measurement units like yarn, paper clips, straws, pencils, blocks, and hands helps kids understand what measurement actually means before the ruler shows up and tries to look official.

It also builds problem-solving skills because kids have to think through the process: line up the objects, compare the lengths, count carefully, record results, and explain what they noticed.

Monster Math Materials

You do not need anything fancy for this activity. A few basic supplies turn into a full math box of measuring fun.

• Yarn or string
• Number cards
• Paper clips
• Straws or craft sticks
• Newspaper, magazine, or grocery ad
• Blank calendar page or paper marked like a calendar
• Glue stick
• Scissors
• Small paper bag
• Ruler or yardstick
• 3 or 4 small containers in different sizes
• Paper and crayons for recording answers

Before You Start: Set Up a Monster Math Box

Keep the supplies in a shoebox, pencil box, plastic bin, or zipper pouch. Label it “Monster Math” and add new activities as your child grows. This makes it easy to grab for homeschool lessons, classroom centers, rainy days, quiet time, or screen-free practice after school.

You can also add pattern blocks, tangram pieces, counting beans, dice, craft sticks, buttons, and printable number cards to build a more complete hands-on math kit.

Monster Math Problem-Solving Activities

Start with these quick number and problem-solving activities before moving into the measurement section. They warm up counting, number recognition, number words, and spatial thinking.

1. Newspaper Number Hunt

Give your child an old newspaper, magazine, grocery ad, or coupon flyer. Have them search for numbers, cut them out, and glue them to a blank calendar page or a sheet of paper marked like a calendar.

Numbers may vary in size, color, and style, which makes this a great way to show that the same number can look different depending on the font. Two-digit numbers can also be created by combining two separate numbers.

Learning boost: Ask your child to find today’s date, their birthday number, the number 10, or all numbers greater than 20.

2. Count Chairs, Tables and Legs

Walk through your house and count the number of chairs. Then count the number of table legs and chair legs.

For younger kids, count together out loud. For older kids, turn it into a multiplication moment by asking, “If each chair has four legs, how many legs do four chairs have?”

Learning boost: Compare rooms. Which room has the most chair legs? Which room has the fewest?

3. Practice Number Words with Number Cards

Use number cards to practice matching numerals to number words. For example, match 7 with seven, or 12 with twelve.

You can also spread the cards on the table and ask your child to put them in order from smallest to largest.

Learning boost: Call out a number word and have your child slap, point to, or pick up the matching number card.

4. Build Animals with Tangram Pieces

Using your tangram pieces, challenge your child to create as many animals as possible.

Try a cat, bird, fish, dog, rabbit, turtle, or silly made-up monster. This supports geometry, visual-spatial reasoning, creativity, and problem solving.

Learning boost: After your child creates an animal, ask them to trace it and name the shapes they used.

Monster Math Measurement Activities

The development of measurement concepts takes practice. Kids need to compare lengths, weights, capacity, and height using real objects before those ideas feel natural. These activities use direct comparison and nonstandard measurement to help kids build that foundation.

5. Longest Hair, Shortest Hair

Gather your family together and compare hair length. Who has the longest hair? Who has the shortest? Do not forget pets if they are willing to participate in the math lesson without filing a formal complaint.

Have your child line everyone up from shortest hair to longest hair or draw a picture showing the order.

Learning boost: Ask, “How do you know?” Encourage your child to explain whether they compared by looking, touching, or measuring.

6. Length Treasure Hunt with Yarn

Cut 10 different lengths of yarn or string, ranging from about 2 inches to 20 inches. Hand your child one piece at a time and ask them to search around the house for an item that is about the same length.

After they find a match, have them draw each item on paper in order from smallest to longest.

Examples to try:

• A crayon
• A spoon
• A toy car
• A pencil
• A book
• A remote control
• A toothbrush

Learning boost: Use words like longer, shorter, equal, almost, estimate, compare, and order.

7. Draw Straws: Shortest or Longest Wins

Cut straws or craft sticks into different lengths and place them in a paper bag. Add two cards to the bag: one that says shortest and one that says longest.

Each player draws a straw. Then draw one card. If the card says shortest, the player with the shortest straw wins the point. If the card says longest, the player with the longest straw wins.

Return the straws and card to the bag and play several rounds.

Learning boost: Ask your child to compare before deciding. “How can you tell which straw is longer?”

8. Measure the House with Paper Clips

Hook five paper clips together to create a simple measuring chain. Walk around the house and look for items that are exactly, almost, or more than five paper clips long.

Have your child record each item on paper.

Try measuring:

• A pencil
• A fork
• A small book
• A toy
• A shoe
• A hairbrush

Learning boost: Talk about why the paper clips need to stay connected and lined up end to end.

9. Which Container Holds the Most?

Gather 3 or 4 small containers in different sizes. Ask your child to predict which one holds the least and which one holds the most.

Then use water, dry rice, beans, or pom-poms to test the containers and put them in order from smallest capacity to greatest capacity.

Learning boost: Ask your child to make a prediction first, then compare the prediction to the result.

Safety note: Use water only in a sink, bathtub, sensory bin, or outdoor area where spills are not a big deal. Because spills are not a question of if. They are a question of when.

10. Measure Your Family from Smallest to Tallest

Use a ruler, yardstick, or measuring tape to measure each member of your family. Record everyone’s height, then have your child draw a family picture in order from smallest to tallest.

This is a great activity for comparing, ordering, and connecting measurement to real life.

Learning boost: Ask, “Who is taller than you?” and “Who is shorter than you?” For older kids, compare the differences between heights.

Printable Number Cards

Use these number cards for counting practice, number word recognition, ordering, matching, and quick math games.

Ways to Use the Number Cards

• Number match: Match the numeral to the number word.
• Number order: Put the cards in order from smallest to largest.
• Mystery number: Choose one card and give clues until your child guesses it.
• Measure and match: Measure an item, then find the number card that matches the result.
• Greater or less: Draw two cards and compare which number is greater.

Frequently Asked Questions About Monster Math Measurement Activities

What age is this Monster Math activity best for?

This activity is best for preschool through early elementary students. Younger children can compare objects and count with help, while older children can estimate, measure, record results, and explain their thinking.

What is nonstandard measurement?

Nonstandard measurement means measuring with objects instead of standard tools like rulers or measuring tapes. Examples include measuring with paper clips, yarn, craft sticks, straws, blocks, hands, or pencils.

Why should kids use nonstandard measurement before rulers?

Nonstandard measurement helps kids understand what measuring means. They learn to compare, line objects up, count units, and notice length before using inches, feet, centimeters, or rulers.

Can I use this activity in a classroom math center?

Yes. Place yarn pieces, paper clip chains, straws, number cards, recording sheets, and a few classroom objects in a bin. Students can rotate through the activities independently or in pairs.

How do I make this activity less messy?

Use a tray or table mat for the yarn, straws, paper clips, and number cards. For the container capacity activity, use pom-poms, counting bears, beans, or dry rice instead of water if you want less cleanup.

Can this be used for homeschool math?

Absolutely. This is a simple, low-prep homeschool math activity that covers counting, number recognition, comparison, measurement, ordering, estimating, and problem solving with everyday household objects.

Final Thoughts: Big Math Learning from Little Supplies
