Addition and Subtraction Quiz 1

This quiz, designed for Year 4 students, aims to test their mental arithmetic skills specifically in adding and subtracting numbers. The objective of the quiz is for students to be able to mentally add a three-digit number to a two-digit number and to subtract a two-digit number from a three-digit number. The quiz consists of ten questions that vary in difficulty and require the students to perform calculations without the aid of a calculator or written working out.

The questions in the quiz present a mix of straightforward addition and subtraction problems. For example, Question 1 asks students to add 305 and 19, while Question 2 challenges them to subtract 99 from 955. The quiz also includes problems with missing numbers that the students must find, such as in Question 4, where they must determine what number subtracted from 425 equals 405. At the end of the quiz, an answer key is provided, allowing students to check their answers and measure their understanding of the concepts. The answers range from simple sums, like 324 in Question 1, to more complex calculations, such as finding that 81 must be added to 639 to make 720 in Question 8.
