2NUMBER SENSE AND FUNCTIONSA. Study the integers and order of operations content standards for your state and do the following:1.List threecontent standards from your state that apply to integers or the order of operations for grades K–6. The three selected Solve multistep word problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding5thGrade:CCSS.MATH.CONTENT.5.OA.A.2Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them. 2.Write a sample problem for eachof the three standards to illustratethe evolution of student understanding.3rdGrade:Find the missing number that makes the equation true: 4 x ___ = 244thGrade: There are 30 bicycles and 10 cars parked in the parking lot. Each bicycle had two wheels and each car has four wheels. How many wheels are there in total?5thGrade:Find 5 times as much as the sum of 6 and 2?3.Provide a solution for eachproblem that demonstrates eachstep orexplains the thinking process involved in determining the solution.3rdGrade: The missing number is 6 because 4 times 6 equals 24.Thinking Process: The students would first look at the equation and see that they will be working with multiplication. Based on their understanding of multiplication, students know that they will need to find out how many groups of 4 will make 24. So students will start making groups of 4 until they have 24 equal and see that 6 groups of 4 makes 24, so 4 x 6 = 24
