Place value - Find 1, 10, 100 more or less than a given number - Starter

The "Fluent in Four" revision activity is designed for Year 4 students to reinforce their understanding of place value and basic arithmetic during the Autumn Term, specifically in Week 3. The activity encourages students to find one, ten, or a hundred more or less than a given number. The tasks involve a variety of exercises, including estimating the value of letters representing numbers in the thousands and solving addition problems. For example, students must calculate the sum of 293 and 341, as well as add 3 tens and 24 ones to 37 ones. The correct answers provided are 634 and 91, respectively.

Another part of the activity focuses on ordering a sequence of numbers from smallest to largest, which helps solidify the concept of numerical order and place value. Students are also asked to answer questions related to a timetable, such as determining the number of sessions on a Monday or identifying the days that are free from judo. The answers indicate that there are three sessions on Monday and two days free from judo. To support learners, the activity suggests allowing answers within 50 of the provided approximate answers for the letter estimation task. This approach encourages estimation skills and helps students develop confidence in their mathematical reasoning.
