Shapes and Arrays:
Partitioning and Tiling Shapes, Arrays, Evens and Odds
Lesson 28
Recognize and Draw Shapes
Content Objectives
🎯 Identify triangles, quadrilaterals, pentagons, and hexagons based on the number of sides and angles they have.
🎯 Identify cubes based on the number and shape of faces that are the same.
🎯 Distinguish among triangles, quadrilaterals, pentagons, and hexagons based on their attributes.
🎯 Draw a shape based on specific attributes.
2.G.A.1Â Â Â Â Â Priority
Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces. Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.
Prior Knowledge
 Identify the sides and angles of a polygon.
Sort objects based on attributes.
Identify and name triangles, circles, squares, and rectangles.
Lesson 29:
Understand Partitioning Shapes into Halves, Thirds, and Fourths
Content Objectives
🎯 Identify and name halves, thirds and fourths as parts into which a shape is divided.
🎯 Recognize that fractional parts are equal in size.
🎯 Understand that the more parts a whole is divided into, the smaller the size of each part.
2.G.A.3Â Â Â Â Â Priority
Partition circles and rectangles into two, three, or 4 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.
Prior Knowledge
Recognize halves of a whole.
Lesson 30:
Partition Rectangles
Content Objectives
🎯 Analyze an array of squares with no gaps or overlaps.
🎯 Determine the number of squares used to partition a rectangle.
🎯 Make an array of squares to fit a rectangular shape.
2.G.A.2 Â Â Â Â Â Â Â Supporting
Partition a rectangle into rows and columns of same-size squares and count to find the total number of them.
Prior Knowledge
Know that an array is organized in same-size rows and columns.
Compose a shape from a different shape.
Know the attributes of a square and a rectangle.

Lesson 31:
Add Using Arrays
Content Objectives
🎯 Describe an array of up to 5 rows and 5 columns.
🎯 Calculate the number of items in an array using repeated addition and skip-
  counting.
🎯 Write an equation to express the sum of items in an array.
2.OA.C.4 Â Â Â Â Â Â Â Supporting
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.
Prior Knowledge
Add 3 one-digit numbers.
Visually recognize groups of 2 through 6. (subitize)
Skip-count by fives.
Write an addition equation.

Lesson 32:
Even and Odd Numbers
Content Objectives
🎯 Identify odd and even numbers.
🎯 Relate doubles and doubles 1+1 facts to odd and even numbers.
🎯 Use skip-counting by twos to identify odd and even numbers.
2.OA.C.3 Â Â Â Â Â Â Â Supporting
Determine whether a group of
objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends.
Prior Knowledge
Know doubles facts to 20.
Understand the meaning of equal groups.
