One such math activity is talking about a child's favorite food and its cost. Because most food prices are not rounded, this activity requires the use of decimals. For example, if one item costs $3.49, you can ask a child much six will cost. If five are bought and you use two, you can ask a child to compute how much the difference (three) is worth. You can also ask what the difference in price is between two items and how much change there will be if you pay with $50.
When out shopping, ask your child the price of a sales item. For example, if the original price is $99.99, ask what the price is with a 50 percent discount. Another stimulating activity is to find recipes that are written for a certain number of people and then ask the child to calculate the correct amount of ingredients for different numbers of people.
You can ask children to write down how long they spend each day on various activities -- for example, sleeping, eating, playing, watching television and doing homework. Then you can ask them to recalculate their answers in terms of percentages. An extension of this would be to ask them to calculate the answers over longer periods of time -- for example, one week or one month.
It is quite traditional for children to learn to recite their times tables in the form of singing them. This can be extended at home by associating words with answers. For example, as the children in this grade are expected to learn the times table up to 10, the number range is 1 to 100. Words can be associated with each answer in the same way that bingo callers do -- such as, "tickle me, 63," etc. Games can also be made up that are math-related. One suggestion is to use a pack of cards, select one suit and remove those with particular values. For example, if spades were used and the ace is valued as 1, the jack, queen and king could be taken out and the child would calculate the remainder, which would be 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 = 55.
