Addition and Subtraction - Adding 2 three digit numbers (no exchange) - Starter

In a Year 4 mathematics lesson on addition and subtraction, students are presented with a series of exercises to reinforce their understanding of place value and the operations involved in manipulating three-digit numbers. The lesson includes a table where students are prompted to perform calculations such as subtracting four tens, adding five ones, and subtracting two hundred from a given number. To aid in these calculations, place value counters representing thousands, hundreds, tens, and ones are suggested as visual aids. This hands-on approach helps to solidify the concept of place value and the effects of addition and subtraction on different number positions.

An applied problem within the lesson involves a scenario with Pirate Joe, who has a treasure chest containing 562 gold coins. Students are tasked with calculating the total number of gold coins after Joe adds six more bags, each containing 10 coins. This practical example shows the real-world application of addition. Additionally, the lesson covers fractions, with students learning to identify equivalent fractions through pictorial representations and words. For instance, they explore how two-thirds is equivalent to four-sixths, and one quarter is equivalent to two eighths. These activities are designed to develop fluency in mathematical concepts and ensure students can confidently manipulate numbers and understand their relationships.
