Arithmetic

Arithmetic is a branch of mathematics that deals with the study of numbers and the basic operations performed on them. These operations include addition, subtraction, multiplication, and division.

Addition

Addition is the process of combining two or more numbers to find their total. For example, 3 + 4 = 7.

Subtraction

Subtraction is the process of taking one number away from another. For example, 7 - 3 = 4.

Multiplication

Multiplication is the process of repeated addition. For example, 2 x 3 = 6, which means adding 2 three times.

Division

Division is the process of splitting a number into equal parts. For example, 8 ÷ 2 = 4, which means dividing 8 into 2 equal parts.

Arithmetic is fundamental to many other areas of mathematics and is used in everyday life for tasks such as calculating money, measuring, and solving problems.

Number and Operations (NCTM)

Understand numbers, ways of representing numbers, relationships among numbers, and number systems.

Count with understanding and recognize 'how many' in sets of objects.

Develop understanding of the relative position and magnitude of whole numbers and of ordinal and cardinal numbers and their connections.

Develop a sense of whole numbers and represent and use them in flexible ways, including relating, composing, and decomposing numbers.

Connect number words and numerals to the quantities they represent, using various physical models and representations.

Grade 1 Curriculum Focal Points (NCTM)

Number and Operations: Developing an understanding of whole number relationships, including grouping in tens and ones

Children compare and order whole numbers (at least to 100) to develop an understanding of and solve problems involving the relative sizes of these numbers. They think of whole numbers between 10 and 100 in terms of groups of tens and ones (especially recognizing the numbers 11 to 19 as 1 group of ten and particular numbers of ones). They understand the sequential order of the counting numbers and their relative magnitudes and represent numbers on a number line.
