Unit Abstract

In this unit, children learn about attributes of shapes, compose and decompose composite shapes, and divide shapes into halves and fourths. Children also continue to practice telling and writing time, work with bar graphs, and use thier understanding of place value and properties of operations to add and subtract larger numbers. The following big ideas will be covered in this unit:

-Some shapes are flat (2-D) while other shapes are solid (3-D).

-Smaller shapes can be used to compose larger shapes and larger shapes can be decomposed into smaller shapes.

-Composite shapes are made using two or more shapes.

-Partitioning the whole can be thought of as cutting or splitting an amount equally.

-Fractional parts are equal shares or equal-sized portions of a whole.

-Fractional parts have special names that tell how many parts of that size are needed to make the whole. For example, fourths require four parts to make a whole. (halves and fourths)

-The more fractional parts required to make a whole, the smaller the parts. For example, fourths are smaller than halves.

-Mental math can be used to find 10 more or 10 less of a given two-digit number.

Expectations/Standards
MI: Mathematics
MI: Grade 1
Number & Operations in Base Ten
1.NBT.B. Understand place value.
1.NBT.B.2a. 10 can be thought of as a bundle of ten ones — called a “ten.”
1.NBT.C. Use place value understanding and properties of operations to add and subtract.
1.NBT.C.5. Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used.
Measurement & Data
1.MD.B. Tell and write time.
1.MD.B.3. Tell and write time in hours and half-hours using analog and digital clocks.
1.MD.C. Represent and interpret data.
1.MD.C.4. Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.
Geometry
1.G.A. Reason with shapes and their attributes.
1.G.A.1. Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size) ; build and draw shapes to possess defining attributes.
1.G.A.3. Partition circles and rectangles into two and four equal shares, describe the shares using the words halves, fourths, and quarters, and use the phrases half of, fourth of, and quarter of. Describe the whole as two of, or four of the shares. Understand for these examples that decomposing into more equal shares creates smaller shares.

Concepts from Previous Units

- The defining attributes of shapes are always present features that classify a particular object.

- The non-defining attributes are features that may be present, but do not identify what the shape is called.

- Some shapes have sides, angles, and faces which can be counted.

-An analog and digital clock can be used to tell time to the nearest half hour.

- Collections can be separated into equal groups of ten objects and can be counted by tens.

- Numbers larger than 10 can be represented in terms of tens and ones.

Connections to Upcoming Units

-Thirds require three parts to make a whole. (Second grade)

-A quadrilateral is a polygon with 4 sides. (Second grade)

-Mental math can be used to find multiples of 10 more or 10 less of a given two-digit number.

Lesson Plan Sequence

The following lesson plan sequence is obtained from Everyday Mathematics 4. Each lesson is aligned with a learning objective to inform the teachers on what students should be able to at the end of the lesson. The student objective informs the students of their learning goals for the day and it should be reviewed before, during and at the end of the lesson. Each lesson includes a mathematics task that should be implemented to meet the learning objectives. Teachers can select from the practice opportunities to reinforce the learning goals of the day.

Language Support

The following language supports are for English Language Learners but could also be used to support any struggling learner in mathematics. The strategies are obtained from the SIOP model. The language objectives will support students' academic language development. The sentence stems and starters provides the support many students need to be able to participate in discussions and writing about mathematics.
