This worksheet challenges young mathematicians to hone their math skills by solving a set of problems on adding hundredths less than 10. When adding decimals, students line up the decimal points and add extra zeros to the right of the number so that each decimal has the same number of digits. Students then add digits at each place to find the sum. In each problem, the numbers are laid out in the horizontal format. Students should try to use different strategies involving composing and decomposing numbers to solve these problems. This will help them develop flexibility and fluency.
