Subject: Math Grade: 3
Standard: #1
Number Sense
Key Concept:
#3 Words, models, and expanded form can be used to represent numbers up
to 1,000.
Generalization:
The value of the number depends on the place it holds.
Background:
Previously, the students have been working with a partner using a place
value mat and place value models and there has been some teacher-guided
instruction.
Tiered according to readiness
Tier I: Partner game. Each player has a “place value kit.” (place value chart, numerals 0-9 on cards; Each player shuffles his/her numeral cards, places them facedown in a stack. In turn, each student pulls a card from his/her stack and places it in a column on his/her p.v. chart, trying to form the highest (or lowest) number possible. Play continues until each player forms a 4-digit number. Students compare numbers and player with the highest (or lowest) value earns a point for the round. Students continue to play rounds until the end of game time. The student with the most points wins.
Tier II:
Students work in a small group (s).
Each student has a set if $1,000 bills, $100 bills, $10 bills, and $1
bills. Teacher has prepared a chart of
picture items and prices. Object is to
look at a price tag and use their money to make the model of that cost. Example:
$2,659 = 2 - $1,000 bills, 6- $100 bills, 5-$10 bills and 9-$1
bills. After each price is made with
money, students can self- check with
answer key.
Tier I: Each
student has a “worksheet” with 3 buses on it.
Each bus has 4 windows. Bus #1
is ones, bus #2 is tens, and bus #3 is hundreds. Each student is given 12 cards with a number on it. Each number has an underlined digit. 742, 830, 903. Students place the number cards according to
the place value of the underlined digit on the correct bus window.
Assessment:
Teacher observation/student participation.
