Title – Measuring Different Dog Biscuits
By – Nancy Paniagua
Primary Subject – Math

TEKS: Measurement.

A) Estimate and measure length, capacity, and weight of objects using nonstandard units.

Learning Objectives:

• Use a measurement scale
• Make an adequate estimate of either the weight or the length
• Record the data on a sheet of paper (provide worksheet)

List of Materials Needed:

• Measurement Scale
• Dog Biscuits
• Worksheet
• Measuring Tape

Pre-Activity Preparation:

Put a measurement scale on student’s desk; 1 per group, and a measuring tape; 1 per group.

Transition:

The students will work with their table in groups of four

Establishing Set/Motivation/Introduction:

Ask what kind of foods do dogs eat, and then show them the dog biscuits and emphasize the different sizes of each one.

Learning Experiences/Presentation/Procedure:

• Ask about the kind of foods dog eat.(Go in detail: How many of you have a dog? Do you give your dog treats? Make sure they understand what dog biscuits are for.)
• Show them the dog biscuits.
• Emphasize that they are different sizes and their weight varies.
• Tell students that today we are going to find out the weight and the length of 8 different dog biscuits and their size.
• When everything is clear about the activity, establish some rules like: take turns using the equipment among their groups.
• Give each student a worksheet so they can record the data they are gathering. (Ask a student to help you pass out the papers.)
• Do an example of measuring and weighing a biscuit.
• Go to the front of the room and show them how to record the data on their paper on the white board. But before you let them on their own, make sure they understand where to begin to measure the dog biscuit.
• After everything is set and crystal clear, let them begin with the activity.
• Once they have begun, go around and check on them to see if they need help.

Closure:

Ask questions about their data. Ask each group which one was the heaviest, the longest and vice-versa: which dog biscuit was the lightest and smallest. Give each student a bag so they can take the biscuits to their dogs.
