Numbers and Place Value (Class 3)

What this worksheet covers

This is a fifteen-question practice worksheet on numbers and place value for Class 3, written to the pattern of the SOF International Mathematics Olympiad (IMO). It carries 21 marks and is designed to be attempted in 40 minutes, split across three sections — Mathematical Reasoning, Everyday Mathematics and Reasoning and Achievers Section. Every question is multiple choice with exactly one correct option, and every one comes with a fully worked solution rather than just an answer key — so a child who gets one wrong can see where the reasoning went astray instead of only learning that it did.

Skills your child practises

Sample questions from this worksheet

1. 1. What is the place value of 7 in 4735?

   • A7
   • B70
   • C700correct
   • D7000
   Solution: Reading from the right, 5 is in the ones place, 3 in the tens, 7 in the hundreds and 4 in the thousands. So the place value of 7 is 7 × 100 = 700.

2. 2. What is the predecessor of 1000?

   • A1001
   • B999correct
   • C900
   • D99
   Solution: The predecessor is the number just before. 1000 − 1 = 999.

3. 3. Using the digits 4, 0, 7 and 2 once each, what is the smallest four-digit number that can be formed?

   • A0247
   • B2047correct
   • C2074
   • D4027
   Solution: To make the smallest number, put the smallest digits at the front. But a four-digit number cannot begin with 0, so the smallest non-zero digit, 2, goes in the thousands place and the 0 goes next.
   This gives 2, 0, 4, 7 = 2047.
