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

The 45 hands-on task cards and corresponding record sheets give kids practice measuring and comparing weight using a simple balance.

---------------------->Bundle with all of my STEM challenges and save!<----------------

In the first 30 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.

NOTE ON MASS vs. WEIGHT

The set now also includes an alternate version of the cards that refers to "mass" instead of "weight".
