Answer Key

What a ledger record contains

Section A: Quick Questions

B — Sender, receiver and amount

A — Ben

A — 20 coins

B — 2 records, one per transaction

A — Sender: Mia, Receiver: Leo, Amount: 15

Section B: Match the Pairs

Sender: Ava → Shows who the money came from in this ledger record

Amount: 25 → Shows how much money was sent in this ledger record

A ledger record names the sender, the receiver and the amount → Ava -> Liam : 10

Each transaction gets its own record, so two payments need two lines → Ava -> Liam : 10 Mia -> Noah : 5

Ava -> Liam → The amount is missing. A ledger record must also say how much money was sent.

Ava -> Liam, Mia : 10, 20 → Two transactions are squashed into one record. Each transaction needs its own record with one sender, one receiver and one amount.

Section C: Definitions

ledger record — One entry in a ledger that states who sent the money (sender), who received it (receiver) and how much was sent (amount). Each transaction gets its own record.

Section D: Fill in the Blanks

record: sender=Ava, receiver=Ben, amount=20

Ava pays Ben 20 coins
record: sender=Ava, receiver=Ben, amount=20

Ava pays Ben 20 coins
Zoe pays Max 5 coins
records needed: 2

Section E: Spot the Error

B — The comment says Zoe sends the money, so Zoe is the sender. The line should be sender: Zoe. Max is the receiver.

D — The transaction sends 8 coins, so the amount in the record must be 8. The line should be amount: 8.

D — Omar receives the money, so he is the receiver. Lily is the sender and cannot also be the receiver. The line should be receiver: Omar.

C — Every ledger record must state the amount as well as the sender and receiver. The amount is missing. The line should be Record 2: Cai > Dee, 9.

B — Each transaction gets its own record. Jo's two payments must not be merged into one record. The line should be Record 1: Jo > Sam, 6.
