Divide Decimal Numbers

TEKS Math: 5.3.F

(F) Represent quotients of decimals to the hundredths, up to four-digit dividends and two-digit whole number divisors, using objects and pictorial models, including area models

5.3.G

(G) Solve for quotients of decimals to the hundredths, up to four-digit dividends and two-digit whole number divisors, using strategies and algorithms, including the standard algorithm

AU Math: ACMNA154

(Y7) Multiply and divide fractions and decimals using efficient written strategies and digital technologies (ACMNA154)

CCSS Math: 5.NBT.7

5.NBT.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.

This number sense lesson focuses on dividing decimal numbers. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students change the problem into long division form, if necessary, and move the decimal point in the divisor to change it to a whole number, if necessary. Then, move the decimal point in the dividend the same number of places. Finally, they divide the decimal numbers and put a decimal point in the quotient above the decimal point in the dividend. In addition to the lesson, there are four pages of Independent Practice and Periodic Reviews with questions modeled after current adaptive testing items and eight flash cards on changing to long division form.
