In this estimating percentages worksheet, students read a problem that gives the percentage of a dollar amount, for example; 8.6% of $75.09 = $5.46. They estimate to determine if they believe the problem is "definitely wrong" or...

Fifth graders estimate perimeter, area, and volume. They measure perimeter and area using nonstandard units of measurement. Students add and subtract non-standard units of measurement. They add mixed numbers and simplify the sum.

Students estimate large quantities. They first practice estimating beans in a tub. They solve a large scale problem using one method of estimating they learned while watching the video, "Eddie Files".

Students, in groups, examine a jar of coins to make both 'guesstimates' and estimates. They compare different estimations and complete a journal entry to summarize their findings.

Students calculate the volume of scale model dinosaurs using a water displacement method. They use formulas to calculate the live mass each of the species of dinosaur. Then they complete and discuss a series of questions.

First graders, in groups, try to figure out which box of name brand raisins have more.

Second graders flip coins and tally the outcomes. They play the You May Already Be a Winner! game with cards under their chairs. Some cards are winners, some might be and the others are not. They play to explain the probability concept.
