Choose a lesson
Work through them in order.
- Not startedMinutes and elapsed timeNextRead each minute on a clock. Measure time. Change between hours and minutes.
- Not startedThe 24-hour clock and durationsNextCheck clock times. Find and compare durations. Allow for breaks. Keep each time’s day.
- Not startedArea and perimeterNextCover the inside for area. Trace the outside for perimeter. Calculate both for rectangles and squares.
- Not startedMissing sides and composite figuresNextFind missing sides, keep area or perimeter equal across changed rectangles, and distinguish inside joins from outside edges.
- Not startedUnit cubes and volumeNextCount three-dimensional space in equal cubes and read a layered cube drawing.
- Not startedTurns, parallel lines and square cornersNextCompare openings with a right angle. Draw parallel and perpendicular lines. Fix wrong drawings.
- Not startedMeasure and draw anglesNextName marked openings, choose the correct protractor scale and construct angles from horizontal or sloping arms.
- Not startedAngles on lines and at a pointNextFind missing angles using turns, intersecting lines, equal parts and overlapping openings, and explain which facts make each method valid.
- Not startedRectangle and square properties and constructionNextUse right angles and equal side lengths to draw and check a rectangle or square.
