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: FirstMaterials/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:
- Organize a set of digits into ascending order.
- Organize a set of digits into descending order.
LESSON:
After downloading the Kid Pix slide show, complete the activity on each slide.
- 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. - Create a group of objects that matches the given tens and ones label. Write the double digit number.
- Generate pictures for a tens and a ones bubble. Write the numbers for each bubble. Write the double digit number.
- Determine how many tens and ones form a large number of objects. Write the double digit number.
- Estimate double digit whole number comparisons.
- Formulate a double digit number through addition.
- Judge whether a double digit number is even or odd.
Assessment:
- Given a double digit number, draw groups of tens and ones with a simple object (such as stars, x’s, hearts).
- Given drawings of objects, group them into tens and ones and write the number.
Modifications:
- 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.
- Use unifix cubes, candy, Teddy Grahams, Valentine heart candy, pennies, macaroni, or cereal to group tens and ones.
- Use Waffles and Skittles to group by tens and ones.
- 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.
- Download clip-art from the internet to create manipulatives for sorting by tens and ones. Cut out and laminate pictures
- Take a three-digit number, draw three columns, and use tally marks to illustrate the number.
- In a math journal (or in a class discussion), tell why breaking up a number into tens and ones is important.
- Divide two numbers into tens and ones. Decide which is greater than the other.
