About This Activity

Maya unrolled a crinkled treasure map revealing two hidden gold locations.

Teacher Tip

Have students write their own two-step word problems using treasure-map story starters — for example, 'Maya found 24 gold coins in Cave 1 and 38 in Cave 2, but gave 15 to her crew' — then label each vocabulary word (SUM, DIFFERENCE, EQUATION, UNKNOWN) directly on their written problem to reinforce CCSS.MATH.3.OA.D.8 connections.

Vocabulary Words

EQUATIONA math sentence showing two amounts are equal, like a treasure trade.

DIFFERENCEWhat remains after you subtract one number from another.

SUMThe total you get after adding all numbers together.

UNKNOWNA missing number in a problem, like a buried chest not yet found.

QUANTITYHow many of something there are, like coins in a chest.

ESTIMATEA smart guess about how many, without counting every single one.

OPERATIONAdding, subtracting, multiplying, or dividing to reach an answer.

VALUEThe worth of a number or object, like gold pieces on a map.
