Mass and capacity - Measure mass activity - Starter

As part of a mathematics activity for Year 3 students during the Summer Term's Week 9, Day 1, the lesson focuses on mastering mass and capacity through a series of engaging exercises. In the 'Fluent in Four - Revision' section, students begin by solving a numerical problem that combines tens, hundreds, and ones to reinforce their understanding of place value and addition. For instance, they are asked to add 7 more to 56 tens, then include 3 hundreds, 6 tens, and 7 ones, leading to the calculation of 567 + 367, which enhances their mental arithmetic skills.

The lesson also includes a geometry component, where students observe a rotated butterfly and determine the degree of its clockwise turn, choosing from options such as a quarter, half, three-quarter, or full turn. This visual exercise helps them grasp the concept of rotation and angles. Additionally, they complete a part-whole model and construct four number sentences that match, further practicing their addition skills with numbers like 975, broken down into 900, 71, and 4. To round off the lesson, the students identify which two shapes out of three options have been divided into thirds, promoting their understanding of fractions and division of shapes. The correct answer in this case is shapes A and C, providing a visual and interactive way to consolidate their knowledge of equal parts.
