STEM Challenge: Linear Measurement


This kid-approved STEM challenge is the perfect addition to your measurement unit or STEM center!

The 60 hands-on task cards and corresponding record sheets give kids practice measuring and comparing length using unifix cubes.

-> Bundle with all of our STEM activity packs and SAVE!

In the first 45 cards, children compare two piles of objects to determine which set is longer.

When they’re ready for a challenge, students then move on to the 15 extension cards.



–> Find objects in the room that are longer or shorter than a given set,

–> Estimate and then measure the length of objects,

–> And decide what type of measuring tool (ruler, measuring tape or yard stick/meter stick) would be best to use in different situations.

Finally, in the final challenge included in the pack, children race Matchbox cars to determine which one travels the farthest.

The STEM challenge pack is so motivating, hands-on and playful! Kids will ask to complete it over and over again.


“My class found this resource really engaging! It was a great way to introduce non standard units of measurement and extending their knowledge of length. Super resource! ” – Rebecca M.

“Definitely one of my favourite activities to do when learning about length. We complete the activities in partners which encourages collaboration as well as STEAM.” – Rachel E.

“I used this resource on my first placement with a kindergarten class and they loved it. Such a great hands on activity that had all the students engaged.” – Lisa A.

“My first graders love these task cards! They are easy for them to understand and work independently/with a partner. I like that there are multiple versions, so they can repeat the center without getting bored. Recording sheets are great!” – Kathleen B.

“These were great activities to help supplement my measurement unit. The students liked measuring a variety of pictures and grasped onto the concepts quickly.” – Chelsey T.

“Amazing resource! So many options to teach linear measurement. The students loved measuring using a variety of materials. They were able to use the material to compare length! They had funding it and were engaged!” – Elisabetta M.
