## Percent – Online Activities

For the classroom

Find the final sales price
Percent 1: Press “the games,” then “Age 10″ and finally, “Percentages 1.” This game gives you a price, the percent discount and students must calculate final sale price. (Prices are in pounds).

Find the original or final price or percent of discount
Percent 2: Press “the games,” then “Age 11″ and then “Percentages 2.” This game gives you two of the following: price, %discount, final price and students calculate the missing piece of information. (Prices are in pounds).

## Thinking Blocks – A Problem Solving Strategy

Thinking Blocks gives you a quick, easy way of teaching students how to model problems with this interactive modeling board.

Set up for ratios, fractions and general solving equations word problems, it has a bank of pre-set word problems, or you can input your own.

Here’s an example of how modeling helps students visualize a problem:

## Decimals – Online Activities

For the classroom

Decimal Jeopardy
Quia Ready made Jeopardy decimal game. Includes rounding to the hundredths place, comparing decimals, comparing whole numbers, place value and number patterns.

For class activity or students

Comparing Decimals and Decimal Operations
Decimal Squares Interactive Games Rope Tug or Decimal Speedway would make a great, quick class activity. Just split your class into 2 teams, select two player, and then have students perform decimal operations. Rope Tug requires comparing decimals and decimal subtraction. Decimal Speedway requires decimal addition and multiplication. Don’t allow the repeat turn option to make this less time consuming. The rest of the games would be better for individual students.

## Fractions – Online Activities

For the classroom

Equivalent Fractions
Equivalent Fractions Memory An online memory game for equivalent fractions that would make a quick, fun class activity, if you have a projector or smart board that is. Just be sure to select level 5.

## Population and percent of change

I was calculating a quadratic fit to update an earlier post I had made about a project idea for Algebra (that integrated quadratic equations with U.S. history). Anyways, while I was using the below data, I was estimating the percent of change of the U.S. population in my head, and then I thought that this would make for an interesting MATH project as well. Students could find the percent of change of every decade, and then they could actually see the figures for certain time periods, such as the Baby Boom of the 1950s (It grew 28,000,000 from 1950 – 1960 as opposed to 14,000,000 from 1960-1970 or 19,000,000 from 1940-1950). I don’t know for sure, but maybe the percent of change would be smaller during the World War or the Civil War? It actually looks like the Civil War didn’t impact the population growth that much. At any rate, wouldn’t it be neat if Math students could relate their percent of change calculations to U.S. Population and historical events that took place during the time period.

Maybe the percent of growth could be seen better with data from every 5 years instead of every 10. I doubt, though, that a census would have been taken more frequently than every decade, and any numbers I may find is probably simply an estimate using some other regression and not truly reflect population variations that may have occurred due to wars, etc. I may make a Math worksheet in regards to this, but it would make a neat Math project for this unit.
