There are several standard exercises which train students to convert percentages, decimals and fractions. Converting percentage to decimals for example is actually as simple as moving the decimal point two places to the left and losing the percent sign "%." Thus 89% is equal to 0ቑ. Expressed in fraction, that would be 89럼. When you drill kids to do this often enough, they learn to do conversion almost instinctively. Ratios and proportions are likewise wonderful math lessons with plenty of interesting practical applications. If three pans of pizza, one kilo of spaghetti, two buckets of chicken can properly feed 20 hungry friends, then how much pizza, spaghetti and chicken does mom need to prepare for birthday party with 30 kids?
Valentine's Day is a great opportunity to give your kids a fun and engaging math activity. There are a number of themed activities and math worksheets available through a quick Internet search. Here's how you can use these resources to give the kids a math lesson that they'll enjoy. You can create a number of other fun activities to bring out the inner_mathematician in a child. For example, if you want to teach kids about the basic ideas of volume and surface area, then Valentine's Day could really lend a hand. Fill three glass jars that differ in size with some heart_shaped candy. Ask the kids to estimate how many sweet treats they think each jar contains. The candy could also help children practice their ability to make tallies, data charts and graphs. Using heart_shaped candy of different colors, ask your child to tally how many of each color there are. You could even use one of the themed math worksheets to help. Once they have created a total for each color, ask your child to compile the totals into a bar chart. If you are feeling kind, then the candy can become a generous reward for the hard work that they've done.
