What is Included
This download contains 2 separate student practice pages along with a complete, ready-to-print teacher answer key.
• Worksheet 1: Multiplying by 10, 100, and 1000
o Section 1: Direct calculation problems featuring a mix of whole numbers, single decimals, and multi-digit decimals (e.g., 27 x 10, 1.26 x 100, 0.0013 x 10).
o Section 2: Missing multiplier challenges where students determine whether 10, 100, or 1000 belongs in the box (e.g., 3.94 x [ ] = 394).
o Section 3: Missing input challenges requiring students to work backward to find the original starting number (e.g., [ ] x 100 = 190).
• Worksheet 2: Dividing by 10, 100, and 1000
o Section 1: Direct division calculations testing digit shifts across multiple place values (e.g., 38 / 10, 5.13 / 1000, 0.01 / 100).
o Section 2: Missing divisor challenges to identify whether the number was scaled down by 10, 100, or 1000 (e.g., 50000 / [ ] = 50).
o Section 3: Missing dividend challenges forcing students to use inverse multiplication logic to solve the equation (e.g., [ ] / 10 = 2.3).
• Complete Answer Keys: Full solutions are included for both pages, matching the layout of the student sheets exactly for quick marking, peer-marking, or student self-assessment.
