Fifth graders look for patterns when multiplying and dividing decimals by powers of 10. The fill-ins include 0.045 × 10², 6,300 ÷ 10², 0.8 × ___ = 8,000, 3.14 × 10³, and 42,500 ÷ 10³. A matching exercise pairs 2.5 × 10², 90,000 ÷ 10³, 0.14 × 10⁴, and 3,600 ÷ 10² with their results 250, 90, 1,400, and 36.
Spotting the count-the-zeros pattern across both decimals and whole numbers gives students a reliable check for the decimal arithmetic that fills the rest of fifth grade.
