Pattern Puzzles (Grade 1)

Master Teacher

Tammy McCarthy

Time Allotment

Three 30-minute class periods

Overview

This lesson will give students the opportunity to build their knowledge of place value in respect to addition and subtraction by watching a short video and doing a series of hands-on activities. The activities will show the students patterns on the hundreds chart with respect to adding and subtracting. At the end of the lesson the students will use these strategies to solve a pattern puzzle.

Subject Matter

Mathematics (Place Value)

Learning Objectives

Students will be able to:

• Identify all of the even numbers on the hundred grid and explain the pattern;
• Use the strategy for adding 10 to any number on the hundred grid;
• Use addition strategies to fill in the missing numbers on the number grid.

South Carolina Standards

Mathematics: Grade 1

I. Understand numbers, ways of representing
   numbers, relationships among numbers,
   and number systems.

E. Connect number words and numerals to the quantities they represent, using various physical models and representations.

3. Identify odd and even numerals up to 100.

III. Compute fluently and make reasonable estimates.

A. Develop and use strategies for whole-number computations, with a focus on addition and subtraction.

1. Explain and describe strategies for addition and subtraction.

B. Develop fluency with basic number combinations for addition and subtraction.

1. Recall basic addition facts with sums up to 18 and the corre-
sponding subtraction facts.

2. Add and subtract pairs of two-digit whole numbers without regrouping.

Video

Math Monsters II, Lesson 3: "Area," is about a group of monsters that want to build a launch pad for their rocket. The launch pad tiles are delivered labeled with numbers 1-100. However while putting the tiles down Mina bumps into Addison and the tiles scatter. They must now use their knowledge of place value to put the tiles down in the correct order.

Web Site

Counter Square by Ambleside C.E. Primary School is a program in which you or the students can move three different shaped and colored counters to cover the hundred grid while looking for patterns.

Materials

For each pair of students:

Activity Sheets

scissors

glue

Equipment

Computer with Internet access

VCR

TV

AverKey

Prep for Teachers

• Students should have some prior knowledge of place value.
  
• Prior to this lesson preview the video to familiarize yourself with the stopping points. Cue the video to the first segment-the end of the dialogue by the woman at the tile store.
  
• Bookmark the Web site:Counter Square by Ambleside C.E. Primary School
  
• Check equipment: TV, VCR, AverKey, and computer connections to make sure they are working correctly.
  
• Make a copy of Activity Sheet 1-A and Activity Sheet 1-B for each pair of students.
  
• Make a copy of Activity Sheet 2 for each student.
  
• When using media, provide students with a Focus for Media Interaction, a specific task to complete and/or information to identify during or after viewing of video segments, Web sites, or other media elements.

Introductory Activity

Step 1: Tell the students that they will be viewing the video, Math Monsters. Provide a Focus for Media Interaction by asking the students how Addison knows where to put the number 20. START the video at the end of the dialogue by the lady at the tile store. PAUSE when you see the big question mark (?) on the screen. Allow students time to respond to your question.

Step 2: Provide a Focus for Media Interaction by asking the students where Addison should put the number 23. RESUME playing the tape and PAUSE the tape when you see a big question mark (?). Provide students with an opportunity to answer your question.

Step 3: Provide a Focus for Media Interaction by asking students to decide where Mina should put her next piece. RESUME playing the tape and PAUSE the tape when you see the big question mark (?). Allow students enough time to answer your question.

Step 4: Play the remainder of the tape to the end.

Learning Activity

Step 1: Go to the bookmarked Web site, Counter Square by Ambleside C.E. Primary School. Make sure the TV monitor and AverKey are on, and all of the students can see the TV monitor.

Step 2: Provide a Focus for Media Interaction by telling the students that while they help you to cover all of the even numbers, they are to look for a pattern.

Step 3: Have the students count by twos slowly while you cover up the even numbers on the hundred grid. Provide them with an opportunity to describe the patterns they see.

Step 4: Clear the hundred grid. Provide a Focus for Media Interaction by telling the students to look for a pattern as you count up 10 from a given number. Have a student pick a number and place a counter over it. Then have the class count up 10 while you move your mouse over the numbers as they say them. Place a counter where they stop. Provide an opportunity to discuss where the counter landed.

Step 5: Repeat Step 4 several times using different numbers until the majority of students see the strategy for adding 10.

Step 6: Clear the board. Provide a Focus for Media Interaction by telling the students to see if they can find the pattern for adding 11. Pick a student to give a number and then place a counter on that number. Have the students count up 11 while you move your mouse over the numbers. Place a counter where they stop. Provide an opportunity for the students to answer the focus question.

Step 7: Repeat Step 6 several times using different numbers until students seem to see the strategy for adding 11.

Community Connections

Invite a carpenter to the class to share how he or she has to add numbers everyday.
