How to Play Ratio Dispatch
- 1
Read the order
Look at the two groups named in the order. The first group supplies the first number on the tag.
- 2
Count and stamp
Count the objects on the tray and pick a number under each label. For All items, count the parcels and tubes together.
- 3
Dispatch
Press Dispatch to check the tag. If a place is marked, revisit the group named there and change its count.
- 4
Next tray
Read the three forms of the ratio after a correct delivery. Use Next tray to continue, then Play again after six deliveries for a fresh run.
Key Features
Count the shipment
Golden parcels and turquoise tubes sit in separate rows of the tray, so you can count each group or combine them for the whole shipment.
Stamp an ordered tag
Choose a count under each of the two group labels. Each choice fills its own place on the shipping tag.
Dispatch and revise
Dispatch sends a correctly tagged tray on its way. If a count is wrong, the game marks the place to review and keeps the tray available for a retry.
Read the same ratio three ways
A successful delivery shows the comparison with a colon, in words, and with a slash, using the same two counts in the same order.
What is Ratio Dispatch?
Ratio Dispatch is a sixth-grade math game about choosing two quantities and writing them in the order requested. Each delivery starts with a tray of parcels and tubes. The order names two groups and the tag records the actual counts from that tray. With 3 parcels and 5 tubes, the ratio of parcels to tubes is 3:5, or 3 to 5, or 3/5. Ask for tubes to parcels and the tag reads 5:3. Ask for parcels to all items and it reads 3:8 because there are 8 objects altogether.
Why Play Ratio Dispatch?
- 1
Keep the order straight
The same objects can produce 3:5 or 5:3. The two labels tell you which group comes first.
- 2
Distinguish parts from the whole
A part-to-part order uses counts from two separate groups. A part-to-whole order includes both groups in its second count.
- 3
Connect words and symbols
Read each successful comparison in words, with a colon, and with a slash while the corresponding group labels are visible.
- 4
Recover from a counting error
Recheck just the marked place and dispatch again. The score stays where it is until the tag is correct.
Frequently Asked Questions
What numbers go on the shipping tag?
Use the actual counts on the tray. If an order names 2 parcels and 4 tubes, the parcel-to-tube tag uses 2:4.
What does All items mean?
All items includes every parcel and every tube. A tray with 3 parcels and 5 tubes has 8 items.
Can I use a keyboard?
Yes. Use Tab to reach number choices and actions, then Enter or Space to select them. You can also tap or click.
What happens when a tag is wrong?
The tray stays in place. Check the highlighted count and try Dispatch again. A mistake resets the streak.
How does scoring work?
Each correct dispatch earns 100 points. The streak tracks consecutive correct dispatches without a mistake. Best and the sound preference are saved in this browser.
