# Math 3.4

Number and operations. The student applies mathematical process standards to develop and use strategies and methods for whole number computations in order to solve problems with efficiency and accuracy. The student is expected to:

• (1) solve with fluency one-step and two-step problems involving addition and subtraction within 1,000 using strategies based on place value, properties of operations, and the relationship between addition and subtraction;
• (A) round to the nearest 10 or 100 or use compatible numbers to estimate solutions to addition and subtraction problems;
• (B) determine the value of a collection of coins and bills;
• (C) determine the total number of objects when equally-sized groups of objects are combined or arranged in arrays up to 10 by 10;
• (D) represent multiplication facts by using a variety of approaches such as repeated addition, equal-sized groups, arrays, area models, equal jumps on a number line, and skip counting;
• (E) recall facts to multiply up to 10 by 10 with automaticity and recall the corresponding division facts;
• (F) use strategies and algorithms, including the standard algorithm, to multiply a two-digit number by a one-digit number. Strategies may include mental math, partial products, and the commutative, associative, and distributive properties;
• (G) determine the number of objects in each group when a set of objects is partitioned into equal shares or a set of objects is shared equally;
• (H) determine if a number is even or odd using divisibility rules;
• (I) determine a quotient using the relationship between multiplication and division; and
• (J) solve one-step and two-step problems involving multiplication and division within 100 using strategies based on objects; pictorial models, including arrays, area models, and equal groups; properties of operations; or recall of facts.
