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

The 60 hands-on task cards and corresponding record sheets give kids practice measuring and comparing weight using a simple balance.

–> Bundle with all of our STEM challenges and save!

In the first 45 cards, children compare two piles of objects to determine which set weighs more and which weighs less.

When they’re ready for a challenge, students then move on to the 15 extension cards that invite them to find objects in the room that weigh more or less than a given set.

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