Four in Four - Subtraction Set C - 3d - 3d with no exchange
Maths Resource Description
The "Four in Four" activity, created by KS2Gems in 2020, is an engaging and fast-paced mathematical challenge tailored for Year 3 students. The task is straightforward yet stimulating: complete four subtraction problems within a four-minute time frame. Each problem involves subtracting one three-digit number from another, with the condition that these calculations do not require any borrowing or exchanging of values. This specific set, labelled as Set C, ensures that students can focus on honing their subtraction skills without the added complexity of exchanging digits.
The worksheets are neatly organized into ten separate sheets, each presenting a new set of four subtraction problems for the students to solve. The subtraction exercises are carefully selected to reinforce the students' understanding of the concept, and the answers are provided for ease of marking. For example, Sheet 1 includes problems such as 674 - 553 and 543 - 231, while Sheet 5 offers calculations like 372 - 121 and 358 - 241. The answers section confirms the correct solutions, such as 265 - 132 equalling 133 and 859 - 649 resulting in 210, allowing both students and educators to quickly assess performance and understanding.
