Probability Bottle Top Lab
A chance bag contains red, green, and pink bottle tops for class probability experiments.
Predict what the bag can produce.
The bag has 10 red, 4 green, and 1 pink bottle top. Learners predict outcomes, draw bottle tops, and compare results.

Bottle tops before chance words
Learners see all bottle tops in the bag before choosing probability words.
List every colour and its count beside the chance words.
Compare colour counts to decide likely and unlikely.
Use real objects or counters before any written shortcut.
Write impossible, possible, likely, unlikely, or certain after checking the bag.
Draw the model so each group, part, or place can be seen.
Point to the colour count before choosing a chance word.
Write the equation only after the visual model is stable.
Starting with a rule before identifying what each object represents.
Ask the learner to point to the unit, group, or column in the picture.
Name the unit first, then rebuild the written statement from the model.
Copying digits or symbols without keeping place value or units attached.
Ask which place, unit, or event each number belongs to.
Write labels beside the numbers before simplifying the answer.
Sort the bottle tops by colour before predicting.
