Give your child an amount, such as $10.37, and a combination of coins and bills. His goal is to use the cash and change to make that amount as fast as possible. His short-term goal is to beat his previous day's time, while a longer-term goal is to move into more-complex amounts of money. He could start with sub-$1 values for a week, then move into slightly higher values each week.
It is faster to count by 2s, 3s, 5s and 10s than it is to count by 1s, especially with larger numbers. This means that counting by multiples is a good long-term goal for your child. Ask her child to count something -- such as how many cows are in a field -- and encourage her to count by multiples. Her first goal could be to confidently count by 2s. The next could be to count by 3s, and so on until she can count by 10s with confidence.
Everyday math skills require basic arithmetic. If you have 10 pieces of wood and someone buys three, you need to immediately understand that you would have seven remaining -- not six, and certainly not four. So, a good long-term goal for your child's everyday math skills is to be able to quickly perform arithmetic functions. A short-term goal can be for him to perform functions at his skill level on a daily basis. Do this by posing hypothetical problems to him until he can solve them without counting, then move on to more-complex hypothetical problems.
Many everyday math problems don't require an exact answer. Rather, the answer just needs to be an estimate. You might need to know if a problem's solution should be more or less than a certain benchmark or to what other numbers it might be close. The goal is to boost your child's skill at making estimates. For example, you could ask, "If I add 7 and 9, will the result be larger or smaller than 20?" Quick confidence with estimation is the goal for this everyday task.
