ILC 2nd Grade Mathematics: Unit 6 Geometry, Time and Money

This is unit 6 of 9 units. The sequence of units is available in the Read Me First Materials in each unit.

• Section A:.Attributes of Shapes
  In this section, students will identify and draw triangles, quadrilaterals, pentagons, and hexagons. Students will learn to name a shape by counting the sides and corners and come to see that, in any shape, the number of corners is the same as the number of sides. Students will also recognize that some shapes, such as rectangles and squares, have “square corners,” the informal language for 90-degree angles. As students identify and draw shapes with given attributes, students will measure length in centimeters and inches. At the end of the section, students will relate two-dimensional (flat) shapes to three-dimensional (solid) shapes. Students will see that flat shapes make up the faces of solid shapes, and students will identify solid shapes based on the flat shapes that make them.
• Section B: Halves, Thirds, and Fourths
  In this section, students will learn that shapes can be partitioned into two, three, or four equal pieces called halves, thirds, and fourths (sometimes called quarters). By the end of the section, students will identify equal-size pieces in shapes, which are partitioned in different ways to build an understanding that equal-size pieces of the same whole do not need to be the same shape. Students will also learn that 2 halves, 3 thirds, and 4 fourths each make up one whole.
• Section C: Time on the Clock
  In this section, you will use your understanding of fourths and quarters to tell time. Students will use “half past”, “quarter past”, and quarter till” to tell time. Students will identify that each hour comes around twice a day and will distinguish between times of day using a.m. and p.m.
• Section D: The Value of Money
  In this section, students will learn about money concepts while continuing to develop fluency with addition and subtraction within 100. Students will identify coins such as quarters, dimes, nickels, and pennies, and find the total value of different coin combinations. Students will solve problems involving dollars and cents and will use the symbols $ and ¢.
