This Heads or Tails Probability Worksheet has 3rd graders predict, flip a coin ten times, and tally the results, then explain why each flip is equally likely. Answer key included.
The Are You Certain? Probability Worksheet gives 3rd graders playful, real-world practice deciding whether everyday events are certain, likely, possible, unlikely, or impossible. Includes a complete answer key for fast, no-prep probability review.
Certain, likely or no way?
Third graders learn to describe how likely something is to happen using words: certain, likely, equally likely, unlikely and impossible. Will the sun rise tomorrow? Certain! Will it snow in July in Florida? Impossible! They flip coins, spin spinners and pull colored cubes from bags, then record results in tally charts. Many start to describe chances with simple fractions, like 1 out of 2 for heads. The click moment is predicting which color will win a spinner game, then testing it.
Probability is best learned by predicting, testing and talking about what happened.
Draw a line on the board from impossible to certain. Read events aloud and have kids place sticky notes where they belong: "A dog will talk," "We will have lunch today." Arguing about the middle spots is where the best thinking happens.
Why it works: children learn more from words and pictures together than from words alone (Mayer, 2009).

Why it works: the U.S. Department of Education's guide for teaching elementary math recommends moving from hands-on objects to drawings to numbers.

Why it works: using clear, consistent math words out loud is one of the U.S. Department of Education's recommendations for elementary math.

It's describing how likely something is to happen, using words like certain, likely, unlikely and impossible. Kids test their predictions with coins, spinners and dice.
Ask how likely something is: "Will it rain today?" Use a scale from impossible to certain. Games with coins and dice make it concrete.
It means two outcomes have the same chance. Heads and tails on a coin are equally likely.
Many schools introduce probability words and simple experiments in 3rd grade, often within data and graphing units. Number-based probability comes later in middle school.
