Common Core State Standards alignment
Grade 5 > Standards for Mathematical Practice > Number & Operations in Base Ten > Understand the place value system > CCSS.MATH.CONTENT.5.NBT.A.2
Explain patterns in the number of zeros of the product when multiplying a number by powers of 10, and explain patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of 10. Use whole-number exponents to denote powers of 10.
Grade 5 > Standards for Mathematical Practice > Number & Operations in Base Ten > Understand the place value system > CCSS.MATH.CONTENT.5.NBT.A.4
Use place value understanding to round decimals to any place.
Grade 5 > Standards for Mathematical Practice > Number & Operations in Base Ten > Perform operations with multi-digit whole numbers and with decimals to hundredths > CCSS.MATH.CONTENT.5.NBT.B.7
Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.
Grade 6 > Standards for Mathematical Practice > Ratios & Proportional Relationships > Understand ratio concepts and use ratio reasoning to solve problems > CCSS.MATH.CONTENT.6.RP.A.3 > CCSS.MATH.CONTENT.6.RP.A.3.C
Find a percent of a quantity as a rate per 100 (e.g., 30% of a quantity means 30/100 times the quantity); solve problems involving finding the whole, given a part and the percent.
