Concept Map: Everything with a place...even numbers!

Everything with a place.... even numbers!

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.1a 100 can be thought of as a bundle of ten tens — called a “hundred.”

    CCSS.Math.Content.2.NBT.A.1b 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).

I. Review numbers

Discover what the class knows going into the lesson on place value. What do they know as a group about numbers, counting, and if anything, on place value.

A. Group

each individual table takes turns counting as a group in increments of 10 until 100 is reached. (table 1:1-10, table 2:10-20, etc.)

B. Individual discussion

Give the class a number and ask a random student how it is read and how he or she knows.

II. See it:

Place Value tutorial

A. Visualize chart

Show visual on the board of place value using simple illustration of place value cards.

B. Connect chart to base-ten

Connect the visual to base-ten blocks. What is the equivalent of place value card to blocks? Show this visually in front of class

III. Touch it:

Base-ten blocks

  -  CCSS.Math.Content.2.NBT.A.1a 100 can be thought of as a bundle of ten tens — called a “hundred.”

  -  CCSS.Math.Content.2.NBT.A.1b 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).

A. Define: meaning of "100"

What exactly is one-hundred? What does the term "one-hundred" mean?

B. Count

Each student breaks down their understanding by showing you with blocks. 

IV. Write it

Hands on activity for students to lead peers in classroom learning. 1 student (previous best participants) from each table takes on this "leadership" activity.

A. Student-led participation

Each student chosen will go to the front of the classroom and write a 3-digit number on the board for the class to identify and show with his or her own individual blocks.

B. Class response

Class responds by using blocks to visualize written numbers. Chosen student waits and then presents correct answer for peers.

V. Know it:

A. Computer application

Learn to apply "place value" in a fun activity online.

B. Evaluate

As students are doing activity, walk around and evaluate the point system and make sure all students understood concept of taught lesson.
