Pre-activities

Read Even Steven & Odd Todd by Kathryn Cristaldi. As story is being read, ask students to make predictions about what will happen next. They make predictions and then read on to see if their predictions were correct. Also a good strategy to use as the story is being read is to write Even Steven’s numbers in one column on the board and Odd Todd’s numbers in another column on the board.

After the story is read, discuss where we see numbers everyday in our lives and how today we are going to determine if these numbers are most like Even Steven’s numbers or Odd Todd’s numbers.

Activities

Part 1: Scoops of Cubes

After reading and discussing Even Steven & Odd Todd by Kathryn Cristaldi ask students to use both hands to scoop connecting cubes from a large container. They then stack the cubes in as many pairs as possible. Ask them to count how many cubes they have. Write “Numbers with Leftover Cubes” on the board or use the computer and a projection device. Say, “Raise your hand if you had one cube left over.” Record their numbers on the board or using a computer projection device and a word processing program. After the list is complete, identify these numbers as odd numbers. Emphasize that all of these had one cube left over. Say, “Raise your hand if you were able to find pairs for all of your cubes.” Tell the students that these numbers are even numbers because they came out even when put into pairs that is, there were none left over. Write a second heading, “Numbers with None Leftover.” As the students tell you their even numbers, write them in the second list.
Collect the cubes.

Ask students to take a second grab of cubes. This time they should use only one hand. Then repeat this procedure.

Part 2: Even or Odd?

Place nine cubes (four cubes in one row and five cubes directly below) on the Strips Master Transparency. Ask, “Are there an even or odd number of cubes on the overhead? How do you know?” Ask a student to count the number of cubes. Emphasize that one cube is not paired. Repeat with other numbers of cubes. Now put the cubes away and color eleven squares (five in one row and six in the other). Ask, “Is this number even or odd? Who can count the number of squares?” Repeat with other numbers. Give each child two of the grid strips from the Strips Master. Ask students to color one strip to show an even number and the other strip to show an odd number. Write two headings, “Even Numbers” and “Odd Numbers”, on the board. As the students finish their work, ask them to tape their models under the appropriate column and write the number each strip represents. When they are finished, ask:

• “What do the strips in the even column have in common?”
• “What do all the strips in the odd column have in common?”
• Are these numbers in order from smallest to largest?”

Students should then complete Even or Odd?

Homework Page: Even or Odd House Search

Assessment Page: Are These Even Steven or Odd Todd?

Computer Activities

1. Using the program Graphers by Sunburst, have students choose an object, stamp the objects, and then sort the objects to determine if they are even or odd.
2. Use Kid Pix Studio Deluxe by Broderbund, have students stamp objects and then count the objects. Then using the alphabet tool, stamp the number on the slide. Also the number word can be placed on the slide using the text tool or the alphabet tool. These can be put together for a class slide show of odd and even numbers.
3. The assessment activity page can also be completed on the computer. Students could count the objects, type the number of the objects in the oval and then type the work odd or even in the text box. Are these Even Steven or Odd Todd
4. Older students could use a hundreds board spreadsheet and shade in the odd numbers one color and the even numbers another color. Attached as an excel document

Raising the Level: (Actually this is Into. to Algebra)

Have students add two groups/numbers together and discover the results.
odd + odd = even
even + even = even
odd + even = odd
even + odd = odd
Student can also explore and discover the results of subtracting odd and even numbers.

Assessment

• Sorting and classifying of objects using graphers.
• Sharing of work done during discussions.
• Informal Assessment: Even or Odd? Activity Page
• Formal Assessment: Are these Even Steven or Odd Todd? Activity Page
• Class Created Kid Pix Slide Show
