Mathematics, Grade 2
Student Learning Profile
Within a well-balanced mathematics curriculum, the primary focal points at Grade 2 are comparing and ordering whole numbers, applying addition and subtraction, and using measurement processes.
The student will:
· Use concrete models to represent, compare, and order whole numbers (through 999), read the numbers, and record the comparisons using numbers and symbols (>, <, =).
· Name fractional parts of a whole object (not to exceed twelfths) and fractional parts of a set of objects when given a concrete representation.
· Recall and apply basic addition facts (sums to 18).
· Select addition or subtraction and solve problems using two-digit numbers, with and without regrouping.
· Determine the value of a collection of coins less than one dollar.
· Model, create, and describe multiplication situations in which equal groups are combined.
· Model, create, and describe division situations in which a set of concrete objects is separated into equal groups.
· Find patterns in numbers such as in a hundreds chart.
· Use patterns in place value to compare and order whole numbers through 999.
· Use patterns to develop strategies to remember basic addition facts.
· Solve subtraction problems related to addition facts (fact families).
· Generate a list of paired numbers based on real-life situations.
· Identify patterns in a list of related number pairs based on a real-life situation and extend the list.
· Identify, describe, and extend patterns to make predictions and to solve problems.
· Identify attributes of any shape or solid.
· Use attributes to describe how two shapes or two solids are alike or different.
· Cut geometric shapes apart and identify the new shapes made.
· Use whole numbers to locate and name points on a line.
· Identify concrete models that approximate standard units of length, capacity, and weight.
· Measure length, capacity, and weight using concrete models that approximate standard units.
· Describe activities that take approximately one second, one minute, and one hour.
· Read a thermometer to gather data.
· Describe time on a clock using hours and minutes.
· Construct picture graphs and bar-type graphs.
· Use data to describe events as more likely or less likely.
· Use tools such as real objects, manipulatives, and technology to solve problems.
· Communicate about mathematics using informal language, objects, words, pictures, numbers, and technology.
· Use a problem-solving plan.
· Use logical reasoning to justify why an answer is reasonable.
· Make generalizations from patterns or sets of examples and non-examples.
