One of the biggest problems is that there are so many different concepts and equations in algebra and in order to be successful you have to understand the entirety of it or you will not be able to figure out which procedure to use. You learned the order of operations years ago and that is one key tool for algebra. This tool allows you to understand which process happens first and so on. PEMDAS is a very valuable tool.
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.
Subtracting fractions is similar to adding fractions. Most of the work involves the denominator. If the denominators of the two fractions are already the same, much of the work is done. Simply subtract the two numerators to get the answer fraction using the same denominator, and then reduce and make a proper fraction.
Using times tables is simple. Practice multiplying the 2’s, 5’s, and 10s first, then the doubles (6 x 6, 7 x 7, 8 x 8). Next, move to each of the fact families: 3’s, 4’s, 6’s, 7s, 8’s, 9’s, 11’s, and 12’s. Start by doing one sheet and see how long it takes you to complete it. Do not worry about how many right or wrong answers you get the first time you complete a worksheet. You will get faster as you become better at multiplying. Do not move to a different fact family without first mastering the previous one.
