1. How many times does the digit 9 occur between the numbers 1 to 100?2. The number of 3 digit numbers formed by using digits 3, 5, 9, taking each digit exactly once, is a. 3 b. 4 c. 5 d. 6Answer:Maths Challenger Critical ThinkingObjective : To build an understanding of place value in 6-digit number.Materials Required: Paper strips of dimensions 12 cm %u00d7 1 cm, markers of different colours, scissors.Steps:1. Take strips of dimensions 12 cm %u00d7 1 cm.2. Fold the strips into 6 equal parts.3. Let the number to be formed is 4,27,569.4. In the first section of the strip 4,00,000 may be written indicates place value of 4 in the given number.4,00,0005. In the section next to it 20,000 should be written which indicates place value of 2 in the given number.4,00,000 20,0006.
