These add decimals with tenths and hundredths worksheets for grade 4 provide four student practice pages plus a complete answer key. Students add decimals with unlike numbers of decimal places, interpret shaded tenths and hundredths models, choose correct sums, solve missing-addend equations, and apply decimal addition in short measurement word problems.
Add Decimals with Tenths and Hundredths Worksheets for Grade 4
The first worksheet, Holiday Decimal Models, contains eight addition problems. Each problem pairs a tenths model with a hundredths grid so students can connect the written addends to visual representations before writing the sum. The values include combinations such as 0.3 + 0.25, 1.2 + 0.34, and 3.1 + 0.46.
The second worksheet, Choose The Decimal Sum, gives eight multiple-choice problems. Students calculate each sum and circle the correct answer from choices A, B, and C. The problems include whole-number parts as well as tenths and hundredths, such as 4.6 + 1.23, 2.05 + 0.72, and 3.86 + 2.1.
The third worksheet, Find The Missing Addend, changes the task from direct addition to unknown-number equations. Across eight items, students determine the decimal that makes an equation true, including 0.52 + __ = 0.89 and __ + 2.09 = 7.49. This page gives practice using addition and subtraction relationships while keeping decimal place values aligned.
Decimal Addition Word Problems and Answer Key
The fourth student page presents four holiday-themed decimal addition stories. Students write an equation and an answer sentence for situations involving ribbon, paper, cocoa, and fruit measurements. The quantities are expressed in meters, liters, and pounds, so students must calculate the decimal total and communicate it with the correct unit.
The fifth page is the Decimal Addition Answer Key. It provides the exact answers for all four student worksheets, covering eight model sums, eight multiple-choice sums, eight missing addends, and four word-problem totals.
