Lesson Plan : Steps To Reading Math Problems

Teacher Name:
 Elena L. Dogar
 Grade 1

 Problem Solving Techniques
 Mathematics: addition subtraction, multiplication and division;other number sense, including numeration and estimation;and the application of these operations and concepts in the work place and other situations
 NM-PROB.PK-12.1: Build new mathematical knowledge through problem solving; NM-PROB.PK-12.2: Solve problems that arise in mathematics and in other contexts; NM-PROB.PK-12.3: Apply and adapt a variety of appropriate strategies to solve problems; NM-PROB.PK-12.4: Monitor and reflect on the process of mathematical problem solving.
 Given word problems, students will identify the sequence of events, using the words first, next, and then to find solutions to the problems.
 Students will use crayons, pictures, and connecting cubes
 Write the words "first", "next", and "then" on the board. Read them aloud to the students. Explain that these words are used to tell the sequence, the order of events.
 Perform the song "If you're happy and you know it" - clap your hands - stomp your feet - shout horray Ask students: What did I do first? What did I do next? What did I do then? Have students repeat. Explain that the sequence of events in a story tells the time order in which the events happened.Tell students that they can often find the sequence of events by looking for time-order words such as first, next, and then.
 Give each student three pictures. In the first picture the girl picks a banana from a fruit bowl, in the second picture the girl peels the banana, and in the third one she eats the banana.Have the students write on the pictures: first, next, and then.Correct them if needed.Read aloud the story "A Family Hike" (Pat and her dad saw many butterflies. First, they saw 6 red ones. Next, they saw 5 blue ones. Then, a bright yellow butterfly landed on Pat's arm!)Have students use red, blue, and yellow connecting cubes to model each addend and form a train. Have students use the cube train to tell what happened first, next, and then. Afterwards, have them write the addition sentence.
 Use chart paper, crayons and connecting cubes. Display an addition story that includes three addends. Circle the numbers in the story to reflect the order of events. Use green for the first number, yellow for the second number, and red for the last number. As you read the story aloud, have the students use green, yellow, and red connecting cubes to model the addition. Ask: How many first? How many next? How many last? How many in all?
Checking For Understanding:
 Give the students a problem to see how can they solve it.First, 4 frogs jump into the pond. Next 5 ducks waddle into the pond. Then, 3 turtles crawl into the pond. How many animals are in the pond? (12) What words told you about the order of events.(first, next, then)
 Why is important to know the words first, next, and then when we are looking at a problem? Relate this to word problems and to a situation in real life to make this more meaningful.
 Students will be tested, using problems that contain a sequence.
Teacher Reflections:
 Were the students successful with the test on word problems? Did they approach the problem with the words first, next, then? Has this helped my students to solve words problems and real life situations? Did I meet the needs of all my students in this lesson? What will I change in the next lesson? What worked?
