Math Knowledge Marble Jar Game

Math Knowledge Marble Jar Game is a Grade 4–5 place-value routine that turns daily number reading into a class goal. The teacher writes a number containing whole-number and decimal places, asks students to identify the digit in a selected position, and adds a marble to the class jar for each correct response. Repeated questions build familiarity with place names and digit value over time.

Use it as a brief whole-class warm-up when you want place-value review to happen consistently without taking over the lesson. The same routine can move between large whole numbers and decimal places as students are ready.
