Add and subtract 5-digit numbers quiz 1

This quiz is designed to test Year 5 students on their ability to add and subtract five-digit numbers, with an emphasis on mental arithmetic. The objective is straightforward: to combine or remove a smaller number from a five-digit number without the use of calculators or written methods. The quiz consists of ten questions, each presenting a different challenge to the students' numerical proficiency.

Questions 1 through 10 vary in complexity, with some requiring the addition of a four-digit number to a five-digit number, while others involve the subtraction of a three- or four-digit number from a five-digit number. For example, question 1 asks students to calculate the sum of 43,305 and 1,250, while question 4 presents a subtraction problem where students must find the missing number that, when subtracted from 17,525, results in 7,125. The quiz concludes with an answer key, providing the correct results for each question, such as 44,555 for question 1 and 33,900 for question 2, allowing students to check their work and understand where they might need further practice.
