The addition worksheets on this page introduce addition math facts, multiple digit addition without regrouping, regrouping, decimals and other concepts designed to foster a mastery of all things addition. All of the worksheets include answer keys, and there are four versions of each worksheet with different problems.
Children will be learning at school how to round up decimals to the nearest whole number. A fun way to practise this at home is to use regular dominos and establish that each piece is a decimal number (so a domino one with 3 dots and 4 dots is 3.4). Encourage them to play with the dominos, but with the rule that they can only, for example, join 2 dominos that are within 1.5 of each other. This will really get them thinking about what each decimal point represents. A number line can also be useful when rounding decimals.
