Title:Double Digit Dilemmas!

Developed byMike Cooper, Pam Dominik, Jana Penney

Sample

Objective: Create sets of tens and ones using concrete objects to describe, compare, and order whole numbers.

Timeline: 45-60 minutes

Content Area: Math / Grade Level: First
Materials/Resources:Kid Pix 4 and
Manipulatives (ex: unifix cubes, Skittles, M&Ms, waffles, Teddy Grahams, pennies, macaroni, Valentine candy hearts, cereal, straws, rubber bands) / Technology Focus:Multimedia
TEKS:
Subject Area - §111.13.1.1 (B)
Technology Applications - §126.2.1.7 (A)

Procedures:

WARM UP:

  1. Organize a set of digits into ascending order.
  2. Organize a set of digits into descending order.

LESSON:
After downloading the Kid Pix slide show, complete the activity on each slide.

  1. Count the objects, label tens and ones, and write the double digit number.
    Label the number of objects in a tens and ones cloud, and write the double digit number.
  2. Create a group of objects that matches the given tens and ones label. Write the double digit number.
  3. Generate pictures for a tens and a ones bubble. Write the numbers for each bubble. Write the double digit number.
  4. Determine how many tens and ones form a large number of objects. Write the double digit number.
  5. Estimate double digit whole number comparisons.
  6. Formulate a double digit number through addition.
  7. Judge whether a double digit number is even or odd.

Assessment:

  1. Given a double digit number, draw groups of tens and ones with a simple object (such as stars, x’s, hearts).
  2. Given drawings of objects, group them into tens and ones and write the number.

Modifications:
  1. Using Dixie cups, skittles, and paper plates, divide a double digit number into tens and ones (put each group of ten into a Dixie cup). Use one paper plate for the tens, and the other for the ones. Write the final number.
  2. Use unifix cubes, candy, Teddy Grahams, Valentine heart candy, pennies, macaroni, or cereal to group tens and ones.
  3. Use Waffles and Skittles to group by tens and ones.
  4. Use straws and rubber bands to group a number by tens and ones. (Do in morning group work to count the days of school!) Group members of class by tens and ones.
/ Extensions:
  1. Download clip-art from the internet to create manipulatives for sorting by tens and ones. Cut out and laminate pictures
  2. Take a three-digit number, draw three columns, and use tally marks to illustrate the number.
  3. In a math journal (or in a class discussion), tell why breaking up a number into tens and ones is important.
  4. Divide two numbers into tens and ones. Decide which is greater than the other.
