Decimals - Adding Decimals (Crossing the Whole) (2) - Worksheet

In Lesson 4 (Part 2) of the worksheet, students are tasked with mastering the skill of adding decimals, particularly focusing on scenarios where the sum crosses a whole number. The worksheet provides a series of decimal addition problems that require the use of the column method to ensure fluency and precision. Examples of the exercises include straightforward additions such as 0.45 + 0.72 and slightly more complex calculations like 0.506 + 0.502. Each problem is designed to help students understand the concept of carrying over when the sum of the decimal places exceeds one whole unit.

Further exercises challenge students to compare the results of different decimal addition problems using comparison symbols. Pairs of number sentences, such as 0.67 + 0.93 and 0.87 + 0.32, are presented side by side for students to determine which sum is greater, less than, or equal to the other. To enhance mental arithmetic skills, the worksheet encourages learners to try solving some problems without writing down their workings. This section is aimed at pushing students to mentally calculate and understand the relative values of decimals in addition, fostering a deeper comprehension of decimal numbers and their properties when combined.
