The Amazing Race
Seventh graders engage in a discussion to determine their experience with traveling. Ask them to describe differences in transportation, currency, culture, food, accommodation, etc. Then they discuss the different expenses one has when...
Curated OER
Finding Percent of Change/ Increase or Decrease
Seventh graders explore the skill of finding the increase and decrease of a quantity. Calculating the increase and decrease is covered by a percent. The proporition for finding a percent is also part of the activity.
Curated OER
Slosh, Dribble, and Plop
Young scholars recognize the need for a standard unit of volume. They estimate and measure to the nearest liter. Also they relate the liter to the familiar everyday containers.
Curated OER
Equal Additions
Students explore the relationships between numbers through the use of "equal addition" and "equal subtraction." Through the use of number sense, they are able to computer addition and subtraction problems mentally. Individually,...

The Divider (whole number remainders)
Third graders use the lesson to support division of whole numbers where there is either no remainder or whole number remainders. They are able to
slit division problems into parts using known multiplication and division facts.
Curated OER
Decimal Fractions of a Set
Sixth graders practice problem solving equations of fractions, ratios and proportions, addition and subtraction stage 6 as well as advanced additive. Emphasis is placed on decimal fractions and then they convert fractions to decimals.
Curated OER
The Multiplier (larger 2-digit by 1-digit numbers)
Young scholars utilize number sense applications to multiply two digit numbers. They use "The Multiplier" and Internet source to partition and solve 2 digit by 1 digit multiplications. Students describe how to solve 2-digit by 1-digit...
Curated OER
What are the Chances: A Game of Chance!
Sixth graders experiment with dice, playing cards, pennies and computer-generated simulations to calculate probability. They use compiled data to make predictions.
Curated OER
How Taxing are Taxes?
Students explore the ways that taxes are levied based on taxable income. They analyze how a new series of tax cuts might affect people of different income levels and their tax rates.
Curated OER
Fractional Blocks
Young scholars explore the concept that fractions can also be considered a ratio. They discover that the fraction bar can be read as "out of." Students practice basic multiplication facts and use patterns to find fractions of shapes.
