Course Description
Grade 2 mathematics is about
extending understanding of base-ten notation;
building fluency with addition and subtraction;
using standard units of measure; and
describing and analyzing shapes.
Quarter 1
Summary:
Students master sums and differences to 20, relate addition and subtraction to metric length and develop place value understanding.
Learning Targets:
I can solve addition and subtraction word problems to find the missing part.
I can estimate lengths using metric units of centimeters and meters.
I can represent whole numbers as lengths from 0 on a number line and represent whole-number sums and differences within 100.
Quarter 2
Summary:
Students build on their place value understanding to compose and decompose numbers.
Students apply place value understanding to add and subtract within 200.
Learning Targets:
I can solve addition and subtraction word problems to find the missing part.
I can fluently add and subtract two one-digit numbers within 20 using mental strategies.
I can understand that the digits of a three-digit number represents the amount of hundreds, tens, and ones.
I can use place value understanding and properties of operations to add and subtract within 1,000.
Quarter 3
Summary:
Students will compose and decompose tens and hundreds within 1,000.
Students will determine equal groups and relate to the basics of multiplication concepts.
Learning Targets:
I can fluently add and subtract two one-digit numbers within 20 using mental strategies.
I can use place value understanding and properties of operations to add and subtract within 1,000.
I can use addition to find the total number of objects in rectangular arrays and write an equation to express the total as a sum of equal parts.
Quarter 4
Summary:
Students will problem solve with length, money and data.
Students will understand part and whole relationships in geometry.
Learning Targets:
I can fluently add and subtract two one-digit numbers within 20 using mental strategies.
I can use addition to find the total number of objects in rectangular arrays and write an equation to express the total as a sum of equal parts.
I can estimate lengths using units of inches, feet, centimeters, and meters.
I can represent whole numbers as lengths from 0 on a number line and represent whole-number sums and differences within 100.
I can generate measurement data by measuring lengths of several objects to the nearest whole unit, or by making repeated measurements of the same object.
I can present data by making a line plot.
I can partition circles and rectangles into two, three, or four equal shares.
