Objective: Learn how to read, write, and skip count 3-digit numbers Instruct students about “hundreds” using
the hundreds model (Figures 1, 2 [A2]) from
How many pieces of chocolate are there altogether? the previous page.
If there are 2 hundreds, it is 200. Pair up students so they can work with
We read 200 as two hundred. 2 hundreds (sets of Figures 1, 2 [A2]).
How many hundreds do you both have?
300 three hundred 400 four hundred 2.
How many squares are there in total?
200.
How do you read 200? Two hundred.
Have students practice counting hundreds
by increasing the number of sets of Figures
1 and 2 [A2] to make 300, 400, 900.
Have them understand that the 2 in 200
represents 200 and the 3 in 300 represents
300. They will learn more about this in
Activity 3.
Have students practice reading and
counting 100 to 900 by combining numbers
1 to 9 with “hundred.” Then, have them
count the number of chocolates.
