Four in Four - Addition Set J - 2dp + 2dp + 1dp

The "Four in Four" activity is a series of arithmetic challenges designed for Year 6 students to enhance their addition skills. Each set, labelled as "Set J," involves adding numbers with two decimal places (2dp) and one decimal place (1dp). Students are tasked with completing four addition problems within a four-minute time frame. This exercise aims to improve both accuracy and speed in mathematical calculations. The problems vary in complexity, starting with simpler sums like "60.44 + 29.37 + 10.3" and progressing to more challenging calculations such as "4126.08 + 587.02 + 398.7". Each sheet contains four unique addition problems for the students to solve.

Accompanying the exercise sheets are the answer sheets, which provide the correct solutions to each of the addition problems presented. These answer keys allow for quick and easy checking of the students' work. For example, the answer to "26.53 + 12.96 + 3.4" is given as "42.89", and the sum of "782.69 + 100.06 + 34.2" is correctly solved as "916.95". The "Four in Four" activity is an efficient and engaging way for students to practice and consolidate their understanding of addition, particularly with numbers involving decimals. The format of the activity, with its time limit and variety of problems, helps to build confidence and proficiency in handling numerical operations.
