NYS Common Core-Math-Grade 2 -Quarter 4

(1) 2.G.1 Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces.5 Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.
(1) 2.G.2 Partition a rectangle into rows and columns of same-size squares and count to find the total number of them.
(1) 2.G.3 Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.

How are geometric shapes similar and different?

Where do we find geometric shapes in the real world?

Geometry: Reason with shapes and their attributes.

(5 weeks)

Students will be able to:

  1. Identify and draw shapes (triangles, quadrilaterals, pentagons, hexagons and cubes) based on their attributes (number of angles/corners, sides, or faces.)

  2. Divide rectangles into rows and columns of equal sized squares.

  3. Divide circles and rectangles into two, three or four equal parts.

  4. Describe equal parts using fraction words. (halves, thirds, half of, one-third, etc.)

Resources

Lessons and Activities:

  1. Shape Reveal / Shape Reveal Chart.docx is an interactive whiteboard resource for facilitating discussion on 2d shape properties. Scratch the panels to uncover sections of the shape then think about what the revealed section shows.

  2. Shape Cutter / Shape Cutter Activity.docx This student interactive, from Illuminations, allows students to explore how they can decompose shapes and recompose them to make other shapes.

  3. I've Seen That Shape Before In these many activities students learn the names of solid geometric shapes and explore their properties.  These activities would be great for small group settings.

  4. Creating Polygons This web-based lesson features an interactive tool for students to use. In Creating Polygons, students make and compare a variety of polygons and describe the properties of the shapes they create.

  5. Shapes and Poetry / Shape Art Worksheet  Students read the poem "Shapes" from A Light in the Attic, by Shel Silverstein, and create their own illustration of the poem. In this lesson, students explore geometric figures and positional words.

  6. Share and Share Alike is a lesson plan that equips students to divide an object into equal parts.

(1) 2.MD.7 Tell and write time from analog and digital clocks to the nearest five minutes, using a.m. and p.m.

Why do we need to tell time in our daily lives?

What is the relationship between analog and digital clocks?

What strategies can help me tell time?

Time

(2.5 weeks)

Students will be able to:

  1. Tell time from an analog clock and digital clock.

(1) 2.OA.4 Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends.

How is addition related to multiplication?

Foundation for Multiplication: Rectangular Arrays

(2.5 weeks)

Students will be able to:

  1. Define an array.

  2. Create rectangular arrays.
