Unit 11: Probability

On Friday, May 29th, students will begin a new unit on Probability as part of the Data Management and Probability strand in Mathematics.  In everyday life, probability is often used to estimate the likelihood of risks and predict future events.  

Students will:

• use the language of probability (likely, unlikely, impossible, certain).
• conduct experiments and predict results.
• use fractions to describe probability.
• use tree diagrams to find probabilities.
• use probability to pose and solve problems.

You can assist your child at home by following some of these suggestions:

• listen to weather forecasts and discuss weather outcomes using probability language.
• play board and card games together.  Compare games that depend on chance to games that depend on skill.
• talk to your child about superstitions. Ex:"Does blowing out a birthday candle and making a wish really change the outcome of an event in the future?"

Measurement Final Test

There will be a Measurement test on Tuesday, May 26.  Students will review lessons in class on Friday and on Monday.

Students should review/ study the following concepts:

• estimating and measuring linear dimensions
• relating units of linear measure
• using decimals to record linear measures
• using a measuring tape to find circumference
• estimating and measuring perimeter and area
• developing and using rules (formulas) for calculating perimeter and area of a rectangle
• solving problems related to length, perimeter, and area

A quiz is coming home today (Tuesday) to be signed.  Students should spend time on any tricky areas for the test.

Energy Project

Students have been learning about:

• forms of energy
• transformations
• renewable and non-renewable energy sources
• conservation

To tie these concepts together, students will be designing and creating an energy-efficient device for a clubhouse.  Most students will be partnered and will go through a design process using a graphic organizer.  Students will be encouraged to use recyclable materials found either at home or at school.  While the device may not function exactly as planned, students should be prepared to explain how it would function and be energy-efficient.

The project will begin either at the end of the week or early next week.  Sketches will be completed and analyzed in class.  A list of required materials will be created for collection at home.

Linear, Perimeter and Area - Measurement Quiz

On Friday, May 15, there will be a quiz for Unit 9.  The following concepts will be covered and should be reviewed:

• choosing appropriate unit of measure
• estimating approximate measures
• converting (mm, cm, dm, m, km)
• comparing  non-standard units of measure
• drawing figures on grid paper and finding area and perimeter
