Minuend a number from which another number will be subtracted – Subtrahend a number to be subtracted from a minuend – Subtraction of whole numbers within 1,000 With or without regrouping Term a number and/or an unknown in an expression separated by an operation symbol(s) – Expression a mathematical phrase, with no equal sign, that may contain a number(s), an unknown(s), and/or an operator(s) – Number sentence a mathematical statement composed of numbers, and/or an unknown(s), and/or an operator(s), and an equality or inequality – symbol Number sentences, or equations, with an equal sign at the beginning or end Ex: 10 = 6 + 4; 6 + 4 = 10 Ex: 6 = 10 4; 10 4 = 6 – – Represent mathematical and real-world problem situations Concrete models Objects represent the quantities described in the problem situation. Base-10 blocks, place value disks, etc. Pictorial models Pictures drawn represent the quantities described in the problem situation. Base-10 pictorials, number lines, strip diagrams, etc. Numbers Numbers represent the quantities described in the problem situation. Oral and written descriptions Explanation of relationship between objects, pictorials, and numbers and the information in the problem situation Solve mathematical and real-world problem situations with the result unknown. One-step problems Connection between information in the problem and problem type Addition result unknown a + b = __ Ex: Part-part-whole whole unknown a + b = __ Ex: Comparison larger quantity unknown a + b = __ Ex: Subtraction result unknown
