Unit 1: Counting Coins and Combinations
 |
This unit focuses on counting and comparing quantities,
composing and decomposing numbers, and understanding the
operations of additions and subtraction. Students
develop strategies for comparing, combining, doubling
quantities, as well as taking one quantity away. They
also achieve fluency with three sets of addition
combinations (10s, +1, +2). During this first unit of
the year, students are introduced to several year-long
classroom routines that offer regular practice with
composing and decomposing numbers; developing visual
images of quantities; counting, collecting, and
analyzing data; and telling time. |

Unit 2: Shapes, Blocks and Symmetry
 |
Students identify two- and three-dimensional shapes,
focus on the properties of rectangles and rectangular
prisms, and identify and create symmetrical designs.
Students also achieve fluency with the doubles addition
combinations. The Shapes software is introduced as a
tool for extending and deepening this work. This tool is
designed for K-2 students to explore how different
shapes go together, experiment with different sorts if
geometric transformations(rotations, translations,
reflections) explore patterning, and investigate
symmetry. |

Unit 3: Stickers, Number Strings and Story Problems
 |
In
this second number unit, students solve problems with
multiple addends and consider whether order matters in
addition. For example, does 7 + 4 + 3 + 6 = 7 + 3 + 4 +
6? Students revisit addition and subtraction story
problems, investigate even and odd numbers, and begin to
make sense of counting by groups and place value (tens
and ones). Work on addition combinations continues as
students achieve fluency with the Near Doubles. |

Unit 4: Pockets, Teeth and Favorite Things
 |
Students engage in all the phases of data analysis as
they pose questions, collect and sort information, and
make representations of data as a way of sharing their
findings with others. They work with Venn diagrams and
line plots, and they read and interpret a variety of
representations of numerical and categorical data.
Students are also assessed on fluency with the + 10
addition combinations. |

Unit 5: How Many Floors, How Many Rooms
 |
In
this unit, students describe and represent ratios, using
tables to represent and predict change, and work with
numeric sequences as they construct and describe
patterns. Students extend repeating patterns and
determine which element of the pattern will be in a
particular position. |

Unit 6: How Many Tens, How Many Ones
 |
Students continue to build their understanding of place
value (ones, tens, hundreds) as they compose and
decompose numbers into tens and ones and work with
contexts and models for the Base-10 number system.
Students apply their work with place value as they play
games that involve composing and decomposing 100 and
solve addition and subtraction problems to 100. There is
continuing work on developing coin equivalencies and
combinations, developing visual images of numbers, and
telling time. |

Unit 7: Parts of a Whole, Parts of a Group
 |
Students investigate what fractions are and the many
ways they can be represented and used. They identify
fractions of a single object (1/2 of a square, 1/4 of a
rectangle, etc.) as well as find fractions of a set (1/2
of 12). Students begin to learn how fractions are
expressed in words and represented using fraction
notation. |

Unit 8: Partners, Teams and Paper Clips
 |
This final number unit of Grade 2 is a culmination of
the number and operations work students have done in
Grade 2. Students refine their strategies for adding and
subtracting numbers as they work toward developing
fluency with addition and subtraction of two-digit
numbers up to 100. They investigate and make
generalizations about what happens when you add even and
odd numbers. They learn the remaining single-digit
addition combinations, achieving fluency with all of the
combinations. Work continues with telling time, place
value, and coin combinations. |

Unit 9: Measuring Length and Time
 |
Students investigate linear measurement as it applies to
length and distance. They work with a variety of linear
units, including standard units of inches, feet, yards,
centimeters, and meters. Students build on their work
with telling time as they measure, record, and calculate
duration of events using timelines and schedules. |
