Adding Decimals with Bar Charts — Easy Worksheet 1
Grade 4 · MathSheets Name: ____________________ Date: __________
Look at each bar chart carefully. Read the decimal value shown on each bar, then add the values asked for in the question.
How to solve
Read the number at the top of each bar to find its value. To add decimals, line up the decimal points and add each place from right to left, just like whole numbers. For example, if the chart shows Mon = 1.4 km and Tue = 2.3 km, add: 1.4 + 2.3 = 3.7 km.

💡 Read the number on top of each bar: Emma is 5.0, Noah is 3.2 and Lily is 1.8. Add them. Line up the decimal points, then work place by place from the right. Tenths: 0 + 2 + 8 = 10. Write 0 and carry 1 to the ones. Ones: 5 + 3 + 1 + 1 = 10. So 5.0 + 3.2 + 1.8 = 10.0, which is the same as 10. The answer is 10.0 hours.
