Grade 7 - Number Sense and Numeration

Standard 7.NSN.1 - Practice estimating positive and negative square roots.

Included Skills:

Quantity Relationships

• represent, compare, and order decimals to hundredths and fractions, using a variety of tools (e.g., number lines, Cuisenaire rods, base ten materials, calculators);

• generate multiples and factors, using a variety of tools and strategies (e.g., identify multiples on a hundreds chart; create rectangles on a geoboard) (Sample problem: List all the rectangles that have an area of 36 cm2 and have whole-number dimensions.);

• identify and compare integers found in real-life contexts (e.g., -10�C is much colder than +5�C);

• represent and order integers, using a variety of tools (e.g., two-colour counters, virtual manipulatives, number lines);

• select and justify the most appropriate representation of a quantity (i.e., fraction, decimal, percent) for a given context (e.g., "I would use a decimal for recording the length or mass of an object, and a fraction for part of an hour.");

• represent perfect squares and square roots, using a variety of tools (e.g., geoboards, connecting cubes, grid paper);

• explain the relationship between exponential notation and the measurement of area and volume (Sample problem: Explain why area is expressed in square units [units2] and volume is expressed in cubic units [units3].).
