Students learn to understand and calculate area and perimeter in 42 multiple-choice activities in 7 levels, starting with rectangles and squares and ending with patterns composed of squares, triangles, other polygons, and circles.
Features:
• 7 levels are: Rectanglia (rectangles and squares), Trianglia I (right, acute, and obtuse triangles, compared to rectangles and other parallelograms), Trianglia II (rotated right, isosceles right, isosceles, equilateral, obtuse, and acute triangles), Quadrilateralia (kite, rhombus, right trapezoid -- or trapezium, isosceles trapezoid, and some odd quadrilaterals), Polygonia (regular and irregular pentagons, hexagons, and octagons), Circlia, and Compositonia (patterns made from other shapes).
• A background grid of square units visually shows the meaning of area in initial activities and reinforces understanding in subsequent selected activities.
• Activities to develop understanding are introduced before mathematical expressions to help students remember the meaning of what they're doing.
• Parallelograms, including rectangles, are described from the beginning using vocabulary of "base" and "height" in order to make language consistent for a wider range of shapes.
• The relationship between different shapes and calculations for area and perimeter is shown through activities that directly compare shapes and their sizes when they share one or more measurements.
• Early activities use integer measurements; later activities, as appropriate, include decimal measurements.
• As activities increase in difficulty, students must pay attention to details by identifying and choosing pertinent information to make appropriate and accurate calculations.
• Requires only single touches to make a choice from multiple options.
• Game-like environment provides immediate feedback in a non-busy setting conducive to thoughtful exploration.
• Self-contained; students will not see ads or have access to in-app purchases or the Internet from within this app.
