Hopping Along the Number Line Competition Rules
1. Each pair consists of a Reader and a Line Runner.
2. One point is added for each second used until the Line Runner clearly states the final answer
as both a fraction greater than 1 and as a mixed number.
3. The Reader must read the entire problem to the runner and cannot simplify the math for the
runner. Failure to read the problem can result in a 5 point addition.
4. The Line Runner must act out all of the operations the Reader reads and must be at the final
location before stating the final answer, both as a fraction greater than 1 and as a mixed
number.
5. The Reader may not at any time show the problem card to the Line Runner.
6. Incorrect answers cause a 10 point addition to the time.
7. 60 is the maximum score for each round.
8. The lowest total score after all rounds is the winner!

).
• Each team/person selects one color of counters to represent them on
the game board.
• The first team or player to go chooses two (2) factors from the bottom
of the board and calls out the product. The team or player will place
a paperclip on each of the factors at the bottom of the page and then
place their counter on the game board in the box representing the
product. If the product shows up twice on the game board, the team
or player must choose which one they want.
• The next team or player now must chose one (and only one) of the
paperclips to move to another factor and call out the product. They
then place their counter in the box representing the product.
• Note: Both paperclips may be placed on the same factor (e.g., 2 x 2
=4).
• Note: Recall equivalent fractions when looking for the product you
would like!

Part 2: Extending the Place Value Chart
So far, you have been representing numbers that are part of a whole with a fraction. We can also
represent these numbers as decimals. When we have fractions representing tenths
hundredths
and
, we call these decimal fractions and we can record these numbers by extending
the place value chart. Look at the chart below and find where the tenths and hundredths are.
Place Value Cards to Represent Decimal Fractions
Note: .1 represents one-tenth and .01 represents one-hundredth.
Use your place value cards to play a game. When your teacher calls out a value, try to be the
first to hold up that place value card.
Part 3: Writing the decimal fractions using place value
Go back to problems 1-9 and represent each fraction using the place value cards. Record what
the decimal fraction name looks like on the line that says “Place Value”.
