What’s in a Gallon?

Teacher: Ms. Barrios, Ms. Benavides, Ms. Gamez, Ms. Hillery, Ms. Moore Date: 3/5/2015 Subject / grade level: 4th Grade Math Materials:

1. Measurement containers with water 2. (per class) Gallon jugs (1), Quarts (4), Pints (8), Cups (16) 3. What’s in a Gallon worksheet 4. Gallon Astronaut worksheet

TEKS: 4.8 Geometry and measurement. The student applies mathematical process standards to select appropriate customary and metric units, strategies, and tools to solve problems involving measurement. The student is expected to:

4.8B convert measurements within the same measurement system, customary or metric, from a smaller unit into a larger unit or a larger unit into a smaller unit when given other equivalent measures represented in a table

(C) solve problems that deal with measurements of length, intervals of time, liquid volumes, mass, and money using addition, subtraction, multiplication, or division as appropriate. ENGAGEMENT. 1) Tell students that they will be exploring how much liquid it takes to make a gallon and the different components that make up a gallon. 2) Ask the students to identify something they know about water, like that it is liquid, it takes any shape, it is wet. Etc. 3) Ask students if they have any idea of how much water the average American uses daily? It is 100 gallons. You can ask them what do people use water for? 4) Then, share that in space astronauts are limited to six gallons of water daily. Ask students to turn and talk with their group about how they think astronauts brush their teeth in space and listen to responses. 5) Tell students you have a video for them to watch about how astronauts brush their teeth to see if their ideas were true.

EXPLORATION 1) The teacher will use volunteers to demonstrate to the students using measurement containers and water that there are:  4 quarts are in a gallon  2 pints in 1 quart and that if there are 4 quarts in a gallon, then there are 8 pints in a gallon  2 cups in 1 pint and if there are 8 pints in a gallon, there are 16 cups in one gallon.  1 cup equals 8 ounces EXPLANATION 1) Lets make a gallon man astronaut! With the students help the teacher will build a gallon man astronaut out of gallon, quart, pint, and cup containers. The class will make a large 1 What’s in a Gallon?

gallon man astronaut, as the students complete their own on paper to refer to as notes. 2) The teacher can pull up the 4th grade formula chart on the smart board or give the students copies of the formula chart. Use the gallon man model to show the students the connections between their formula chart and what they have just done to prove to the students how gallons, quarts, pints, and cups relate. 3) Point out the word capacity and ask the students to think about what this word means. Ask students if they have been in an elevator and seen a sign that says something like, Max capacity 8 people, see what the students think this means and explain to them the word capacity simply means how much stuff something can hold. 4) Have students watch: A cup fills up (capacity) video. https://www.youtube.com/watch? v=E4UC_StFhAk Remind students to pay close attention to how many cups, pints, and quarts are in a gallon. ELABORATION 1) Students will be given a, what’s in a gallon worksheet. 2) With the help of teacher facilitators, the students will use the gallon man and their reference chart to help them solve the tables. 3) The lead teacher may want to demonstrate whole group to get the small groups started. 4) Review student answers.

EVALUATION 1) Students will answer teacher made STAAR formatted questions whole group. 2) Students can vote for answers using sign language, tapping on desks, or giving thumbs up to vote for answers.
