In this section we will discuss about 1 st grade math contents.

1) Understand and use numbers up to 100.
2) Count, read, and write whole numbers to 100.
3) Compare and order whole numbers to 100 by using the symbols for less than(<), equal to (=) , or greater than (>).
4) Represent equivalent forms of the same number through the use of physical models, diagrams, and number expressions (to 20)
(Example: 8 may be represented as 4 + 4, 5 + 3, 2 + 2 + 2 + 2, 10 -2, 11 -3).
5) Count and group object in ones and tens (Expanded form)
(Example: three groups of 10 and 4 equals 34, or 30 + 4).
6) Identify and know the value of coins and show different combinations of coins that equal the same value.( Money)
7) The meaning of addition and solve problems.
8) The meaning of subtraction and solve problems.
9) Addition and subtraction commit them to memory.
10) Count by 2s, 5s, and 10s to 100. Tables
11) Meaning of addition (putting together, increasing) and subtraction (taking away, comparing, finding the difference).
12) Solve addition and subtraction problems with one-and two-digit numbers (Example: 6 + 78 = __ and 58 – 7= __).
13) Find the sum of three one-digit numbers.
(Example : 5 + 8 + 9 =___).
14) Students use estimation strategies in computation and problem solving that involve numbers that use the ones, tens, and hundreds places.
15) Write and solve number sentences from problem situations that express relationships involving addition and subtraction.
16) Understand the meaning of the symbols +, -, =.
17) Create problem situations that might lead to given number sentences involving addition and subtraction.
18) Students use direct comparison and nonstandard units to describe the measurements of objects: Measurements
19) Compare the length, weight, and volume of two or more objects by using direct comparison or a nonstandard unit.
Length, weight and volume
20) Tell time to the nearest half hour and relate time to events (e.g., before/after, shorter/longer).
21) Students identify common geometric figures, classify them by common attributes, and describe their relative position or their location in space: Location and position
22) Identify, describe, and compare triangles, rectangles, squares, and circles, including the faces of three-dimensional objects. Shapes
23) Classify familiar plane and solid objects by common attributes, such as color, position, shape, size, roundness, or number of corners, and explain which attributes are being used for classification.
24) Arrange and describe objects in space by proximity, position, and direction (e.g., near, far, below, above, up, down, behind, in front of, next to, left or right of). Statistics, Data Analysis, and Probability.
25) Students organize, represent, and compare data by category on simple graphs and charts: Graphs
26) Sort objects and data by common attributes and describe the categories.

In short the curriculum in 1 st grade includes 1) Introduction of numbers
2) Addition 3) Subtraction 4) Time 5) Pattern 6) Money 7) Data handling 8) Measurement 9) Probability for (US and UK).
