In this unit, the students will:
- Relate millimetres, centimetres, and metres
- Relate inches to feet and yards
- Justify the choice of millimetres, centimetres, or metres to measure various lengths
- Measure lengths of straight lines and curves, with millimetres, centimetres, or metres
- Recognize length expressed in metric or imperial units
- Approximate a measurement in inches, feet, or yards using centimetres or metres
- Determine the perimeter of polygons
- Determine the length of an unknown side given the perimeter of a polygon
- Identify referents for a centimetre and a metre
- Estimate length by comparing to a benchmark
- Estimate length by visualizing the iteration of a referent for a centimetre or metre
- Investigate relationships between seconds, minutes, and hours using an analog clock
- Relate minutes past the hour to minutes until the next hour
- Describe time of day as a.m.or p.m. relative to 12-hour cycles of day and night
- Tell time using analog and digital clocks
- Express time of day in relation to one 24-hour cycle
Here are some activities you can try with your child:
- Keep a calendar of a family schedule. Encourage your child to refer to the times frequently throughout the day.
- Ask your child to estimate and measure the length, width, height, or perimeter of objects around the house. For example, when your child is setting the table, ask for an estimate, then work together to measure the perimeter of the table, or a place mat
- Encourage your child to use the digital and analog clocks in your home to keep track of the time.
