More Than / Less Than

Turn fact practice into mathematical thinking with this flexible set of expression and comparison cards. Students combine addition and subtraction expressions with comparison symbols and words—such as =, <, >, “is greater than,” “is less than,” and “is equal to”—to build and analyze true mathematical statements.

Instead of answering a single problem, learners analyze and compare expressions, determine their relationship, and explain their reasoning. The result is a deeper understanding of operations and number relationships.

Unlike traditional flashcards that focus on rapid recall of isolated facts, these cards promote reasoning, discussion, and sense-making. Students must evaluate expressions, compare results, and justify their thinking—skills that build number sense and conceptual understanding.

These cards help students:

• Connect addition and subtraction as related operations
• Develop number sense and magnitude comparison
• Strengthen mental math and reasoning
• Practice mathematical argument and discourse
• Recognize equivalent expressions

Because the cards combine expressions, symbols, and words, they also support multilingual learners and developing readers, helping students connect mathematical language with symbolic notation.

Perfect for small groups, math centers, or whole-class discussions, these cards transform basic fact practice into rich mathematical thinking.
