Students are able to read, write, compare, and arrange Hindu-Arabic numbers, Thai numbers, and word form of numbers; tell the cardinal numbers exceeding 100,000 from situations; tell, read, write, compare, and arrange fractions, mixed numbers showing quantity of objects and show objects according to determined fractions, mixed numbers, and mixed numbers which one of the denominators is multiple of another; read, write, compare and arrange decimals with not more than 3 places showing quantity of objects and show positions from situations according to determined decimals; estimate the results from addition, subtraction, multiplication, and division from situations reasonably. Find the value of variable in the number sentence showing addition and subtraction of the cardinal numbers exceeding 100,000 and 0; Find the value of the variable in the number sentence showing the product of 2 numbers not exceeding 6 digits and the number sentence showing the quotient which the dividend not exceeding 6 digits and the divisor not exceeding 2 digits; ; find the result in the combination sentences of addition, subtraction, multiplication and division of cardinal number and 0; construct 2 step problems of cardinal number and 0 while finding the answers; find the sum and difference of fractions and mixed numbers whose one of denominators are multiple of another; show method of finding answers to addition and subtraction word problems of factions and mixed numbers which one of the denominators is multiple of another; find the sum and difference of decimals not more than 3 places; show method of finding answers to 2 step addition and subtraction word problems of decimals not more than 3 places; show the method of finding the answers to the problems involving time; measure and construct an angle by using the protractor; show the method of finding the answers to the word problems involving the perimeter and the area of a quadrilateral; classify types of angles; tell the names of the angles, parts of the angles and write the sign to show the angles; construct a quadrilateral when giving the length of the side; and use the information from a bar chart and a two-way table to find the answer for the word problem. These are for the students to learn; to develop the skills in thinking process, calculation, problem solving, reasoning, and mathematical interpretation to creatively used in daily life; to appreciate and have good attitude towards mathematics; to be able to work systematically and thoroughly with responsibility, judgment, creativity and self-confidence.
