Place Value is the concept that each place in a number has a specific value. As the digits move further towards the left they increase in value. Once students understand place value it will guide them through mathematical thinking for the rest of their school age career. I believe that math can be made easy and fun through hands on learning and engagement in small groups. The class will be taught through playing games, chants, and an interactive powerpoint presentation, and an arts and crafts project. Lesson 1: Skip Counting by 2's and 5's Find the meaning of place value Introduce Vocabulary: ones, tens, hundreds, thousands (not required for second-grade but give an extension on learning) Describing the value of each number - activity Guess the Mystery Number using place value terms. Introducing the base 10 blocks. Lesson 2: Skip count by 5's and 10's Review what is place value Fast Sketch/Make a number game- using base 10 block images Introduce Expanded form 623= 600+20+3 Practice expanded form using dice game: Roll it, Say it, Write it, Expand it! Lesson 3: Skip count by 10's and 100's Roll it, Say it, Write it, Expand it! - Compare numbers who has the greatest value? Who has the smallest value? How do we know? How many ones are in a ten? How many tens are in a 100? How many one hundreds are in 1000? Exchange it up - Game The common core standards for second grade that we will be working on include: CCSS.MATH.CONTENT.2.NBT.A.1 Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones. Understand the following as special cases: CCSS.MATH.CONTENT.2.NBT.A.1.A 100 can be thought of as a bundle of ten tens — called a "hundred." CCSS.MATH.CONTENT.2.NBT.A.1.B The numbers 100, 200, 300, 400, 500, 600, 700, 800, 900 refer to one, two, three, four, five, six, seven, eight, or nine hundreds (and 0 tens and 0 ones). CCSS.MATH.CONTENT.2.NBT.A.2 Count within 1000; skip-count by 5s, 10s, and 100s. CCSS.MATH.CONTENT.2.NBT.A.3 Read and write numbers to 1000 using base-ten numerals, number names, and expanded form. CCSS.MATH.CONTENT.2.NBT.A.4 Compare two three-digit numbers based on meanings of the hundreds, tens, and ones digits, using >, =, and < symbols to record the results of comparisons.
学習到達目標
What we will practice:
What are digits?(0-9)
What are numbers? (comprised of 1 or more digits to have a value)
What is place value?
We are going to play guess that number and write that number.
How can we represent numbers in pictures? (practice drawing numbers using base ten block images)
What is expanded form? (writing numbers for example 613 can also be written as 600+10+3 showing the value of each digit.)
We will also practice writing out numbers in their written form.
We will practice with numbers up to 4 digits. (Ones, Tens, Hundreds, Thousands)
