Teacher Name: | Joann McLucas |
Grade: | Grade 2 |
Subject: | Math |
Topic: | This lesson uses children's literature, place value puzzles, and games to teach place value in a fun and interesting way. This lesson consists of two parts: Part I - Place Value of Digits in a multi-digit numeral and Part II - A Human Place Value |
Content: | Place Value, multi-digit, number system |
Goals: | 1. Use models to explain how the number system is based on 10 and identify the place value of each digit in a multi-digit numeral. 2. Use models and pictures to demonstrate the value of decimal numerals with tenths and hundredths; show decimals as an extension of the base 10 system. |
Objectives: | TLW: identify digits in the tenths and hundredths place. TLW: name the value of digits in a multi-digit numeral. |
Materials: | chalkboards chalk one sock per student Hum book One Grain of Rice Place Value Paper plate |
Introduction: | Read One Grain of Rice stopping at various times to ask questions about the number values in increasing amounts of rice. Example: "On the ninth day, Rani was presented with 256 grains of rice." Stop and ask the student s to write the number and then underline the digit in ones place. . After students write on their chalkboard the answer 6, have students discuss with a neighbor a definition for the ones place. If having trouble, give a hint that the ones place is located how many places and in what direction from the de. Read One Grain of Rice stopping at various times to ask questions about the number values in increasing amounts of rice. Example: "On the ninth day, Rani was presented with 256 grains of rice." Stop and ask the student s to write the number and then underline the digit in ones place. -After students have a definition, write a decimal on the board and next to it write ones . . Read the next sentence in the book, "She had received 511 grains of rice, only enough for a handful." Ask the students to write this number on the chalkboard and underline the digit in the tens place. After students show on chalkboards, turn to their neighbor and discuss a definition for the location of the tens place. Ask students to share their definitions. Write on the board where it is placed. . Continue with numbers throughout the book. . After reading the story, review the chart that has developed throughout the story. Give students additional numbers and ask specific place value questions but also ask students to give how much the digit is worth. |
Practice: | Explain to the students that we are going to try a few practice problems so we can get the hang of it. Give an example: 948 Change this number so there is an 8 in the hundredths place. |
Checking For Understanding: | While playing place value game, every student has at least one answer to the problem. |
