La. Admin. Code tit. 28 § CLXXI-1103

Current through Register Vol. 50, No. 11, November 20, 2024

Section CLXXI-1103 - Number and Operations in Base Ten

A. Recognize that in a multi-digit whole number less than or equal to 1,000,000, a digit in one place represents 10 times what it represents in the place to its right.

Examples: Recognize that 700 / 70=10; in the number 7,246, the 2 represents 200, but in the number 7,426 the 2 represents 20, recognizing that 200 is 10 times as large as 20, by applying concepts of place value and division.

B. Read and write multi-digit whole numbers less than or equal to 1,000,000 using base-ten numerals, number names, and expanded form. Compare two multi-digit numbers less than 1,000,000 based on meanings of the digits in each place, using [GREATER THAN], =, and [LESS THAN] symbols to record the results of comparisons.

C. Use place value understanding to round multi-digit whole numbers, less than or equal to 1,000,000, to any place.

D. Fluently add and subtract multi-digit whole numbers with sums less than or equal to 1,000,000, using the standard algorithm.

E. Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.

F. Find whole-number quotients and remainders with up to four-digit dividends and one-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
