Dividing two-digit numbers by 10 and 100 worksheet

This worksheet is designed to help Key Stage 2 students understand the effects of dividing one or two-digit numbers by 10 and 100. The objective of the activities is to enable students to identify the value of digits in the answer, specifically understanding the place value of ones, tenths, and hundredths. To engage in these activities, students will need various resources including random whole number and decimal number cards, digit cards or dice marked with 10 and 100, and whiteboards with pens for recording their answers.

Activity 1 involves a hands-on approach where students use the provided cards to practice division. They select a card from each pile and divide the number by either 10 or 100 based on the digit card or dice they have. After recording their answers on the whiteboard, they share their results with the class and discuss the strategies they used to find the solution. In Activity 2, the process is reversed; students select a card that represents the answer and roll a dice to determine the division operation that was originally applied. They then work backwards to find the starting number and record the original calculation. For example, if they select the number 84 and the dice indicates a multiplication by 100, they deduce that the starting number was 0.84, and the calculation was 0.84 x 100 = 84. These activities are aimed at reinforcing students' understanding of division and the relationship between division and multiplication when working with base 10 numbers.
