Number Line Fill Up

A game designed to build the concept

of number line proficiency

Materials:

Q^ Number Line Fill Up template

for each player

Q^ Decahedron die (ten-sided, labeled 0–9) or

0–9 spinner (see page 142)

Directions:

1. Each player rolls the decahedron die (or spins the 0–9
   spinner) one time to fi nd his start number.


2. Players decide where to write their start numbers on the
   Number Line Fill Up template.


3. All other rolls (or spins) are numbers shared by all players.


4. Each player records the new numbers one at a time. In this
   game, players are rolling (or spinning) one digit at a time
   to make 2-digit numbers in a counting by ones sequence.
   If a number cannot be used, the player waits for the next
   roll (or spin). Once a number is written, it cannot be moved.


5. The winner is the fi rst player to complete an accurate number
   line chunk including four 2-digit numbers in order.
