Rolling for Number Sense: Even and Odd Numbers
1st Grade - 2nd Grade
Objectives Students will classify numbers as even or odd. Students will recognize that even numbers end in 0, 2, 4, 6 or 8 and odd numbers end in 1, 3, 5, 7 or 9. Students will add numbers with sums up to 12. Materials Needed Dice Manipulatives Paper and pencils “An Odd Valentine” reproducible Red and blue crayons (one of each for each student) Introduction Introduce the concept of odd and even numbers. Tell students that even numbers end in 0, 2, 4, 6 or 8. Odd numbers end in 1, 3, 5, 7 or 9. To help students understand the concept, explain that an even number of objects can be divided equally between two people. Say to students, “If there are four cookies on a plate, two friends can divide them equally—each child can have two cookies. Four is an even number! But if there are three cookies on the plate, the two friends cannot divide them equally. Each child can have one cookie, and they would have to break the third cookie in half. Three is not an even number.”

Pumpkin Measurement
3rd Grade
Objectives Students will listen to a story about pumpkins and learn more about them. Students will learn and understand measurement vocabulary words. Students will estimate—and then measure—the weight, height, circumference, radius and diameter of a pumpkin. Materials Needed Pumpkins by Ken Robbins Small- to medium-sized pumpkins (one for each small group of three to four students and one medium pumpkin for the class) Pumpkins should vary in size as much as possible. Scale Sharp knife (for teacher or adult use only) Rulers String or yarn Pencils Pumpkin Measurement Record Sheet Introduction Read aloud Pumpkins by Ken Robbins. Hold up a medium-sized pumpkin and ask students to estimate, or guess, how much the pumpkin weighs. (Students’ estimates will probably vary widely.) Explain to students that having a starting point of knowledge before estimating will help estimates be more accurate. For example, if students know how much the pumpkin in your hands weighs, this knowledge will help them estimate the weight of smaller or larger pumpkins. Weigh your pumpkin on a scale and tell students the weight. Explain that you’ll be using this measurement in the next activity.

Bundles of Tens: Place Value Lesson
1st Grade - 2nd Grade
Objective CCSS Math/Number and Operations in Base 10/Understand Place Value: 1.NBT.2: Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases: 10 can be thought of as a bundle of ten ones—called a “ten.” The numbers from 11 to 19 are composed of a ten and one, two, three, four, five, six, seven, eight or nine ones. The numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 refer to one, two, three, four, five, six, seven, eight or nine tens (and 0 ones). Materials Needed A Fair Bear Share by Stuart J. Murphy Double-Sided Counters Colored Craft Sticks Craft Sticks (plain) Bundles of 10 recording sheet Place Value Match-Up cards Document camera or chart paper Rubber bands Best-Buy Scissors Introduction Read aloud A Fair Bear Share by Stuart J. Murphy. Pause to point out how the bears count nuts, seeds and berries by putting them in groups of tens with the “extras,” or ones, left over. As you point out the bears’ process, model the way they group nuts, seeds and berries: Use double-sided counters on a document camera or chart to show how the bundling of tens and ones takes place. (For example, on page 13, show how the first cub has 21—two piles of 10 with 1 left over.)
