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

either adding to numbers already

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

must draw additional

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.
