Addition and subtraction - Add and subtract 100s word problems - Starter

In a Year 3 mathematics lesson focusing on addition and subtraction, students are presented with a range of engaging activities to develop their numerical fluency. One task involves using a number line to solve a subtraction problem, where the children must subtract 16 from 62. Another exercise asks them to find a missing number in an addition equation to make the total 74, starting with the number 46. These exercises are designed to reinforce mental arithmetic strategies, such as subtracting ones before tens or partitioning ones to count back to the nearest ten before subtracting the tens.

The lesson also includes a practical application of maths skills through a real-world context, where students use a tally chart to help them complete a pictogram, enhancing their data handling abilities. This visual representation of information is linked to the number of books read by different year groups. Additionally, the lesson incorporates comparative word problems that require the children to equate the weight of doughnuts to strawberries, further challenging their problem-solving skills. These varied activities not only aim to boost the children's confidence in basic arithmetic but also encourage them to apply their knowledge to different scenarios, fostering a deeper understanding of mathematical concepts.
