100 Board Activities

Rounding to the Nearest 10 (Up or Down)
For this activity, students can work with a partner or tegether
as a teacher directed class lesson.
Each student will need 1 board and 1 color tile.
The teacher or student partner calls out a number 1-100. The
student(s) will then cover
that number on their board and determine which "10" they are
closer to. This is a visual way for
students to practice rounding to nearest 10.

Odd or Even Numerals
For this activity, the class works together to follow the
teacher's instructions.
After introducing the concept of "odd" and "even" numbers, ask
students
to cover 10 odd or 10 even numbers from 30 to 50 on their 100's
board. Discuss
what they see when they are finished.

Hundreds Board Hustle
Use a penny and the hundreds board to make 12 addition problems.
Toss the penny on the board and write down the first number.
Toss the penny on the board and write down the second number.
Add the numbers together. Then make another problem.

Number Scrabble
This is a game for two or three players.
Select ten numeral tiles at random and place them in their
correct position on the
blank side of the humdred board. Divide up the remaining tiles
between the players.
The game is played like Scrabble. Each player may place a tile
before, after, avove, or below
a numeral already on the board. Players may place only one tile
per turn. Players who
cannot place a tile must pass. The game continues until a
player wins by running out of tiles.

Keep Picking
This is a number-order game for two to four players. Each
player randomly picks
ten numeral tiles and places them face-up. Place the remaining
tiles in a paper bag.
Players take turns placing their tiles in sequence on the blank
side of the humdred board, either
horizontally or vertically.
Each player may place as many tiles as possible each turn by
on the board or by beginning a new sequence.(Players must have
two or more numbers to start
a new sequence.)
Players who cannot place a tile from among the ones they have
tiles from the bag until aplay can be made. The first player to
use all of his or her tiles wins.

Tens and Ones Bingo
One student is chosen as the caller. The other students cover
the numbers with transparent
counters. The caller places the numeral tiles 1 to 100 in a
bag. Drawing on tile at a time, the
caller calls out the numbers as tens and ones (43 would be
called 4 tens and 3 ones))The first
student to complete a full row either horizontally or vertically
is the winner.

Let's Get 100
This is a game for two players. Players start on space 1 of the
hundreds board and take turns rolling a
(1-6) die. The number rolled indicate the number of spaces to
move forward. Before moving, the
player must state the addition sentence that represents the
move. (For example: on 1, roll 4, say 1+4=5.
on 22, rolls 3, says 22+3=25). The first player to land on or
pass 100 is the winner.

The game can be played starting at 100 and working backward--for
subtraction.
