This worksheet helps students strengthen their understanding of place value and number bonds to 1 using tenths, hundredths, and thousandths.
Section A focuses on tenths, requiring learners to find missing values in simple addition and subtraction sentences that total 1.
Section B shifts focus to hundredths, reinforcing decimal complements.
Section C advances to thousandths with slightly more complex calculations.
In Section D, students match decimal pairs that sum to 1, identify which two numbers in a list make 1, and complete addition pyramids where each brick represents the total of the two below it. This hands-on practice develops mental fluency with decimal complements and supports learners in mastering accurate decimal operations.
