How many different ways can you divide 2345 by 5?
Big Ideas:
Unit 1 instructional time is focused on these priority standards:
4.NBT.B.5 Use place value understanding and properties of operations to perform multidigit arithmetic. Multiply a whole number of up to four digits by a onedigit whole number, and multiply two twodigit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
4.NBT.B.6 Use place value understanding and properties of operations to perform multidigit arithmetic. Find wholenumber quotients and remainders with up to fourdigit dividends and onedigit 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.
Unit 1 instructions is supported by these standards:
4.NBT.A.1 Recognize that in a multidigit whole number, a digit in one place represents ten times what it represents in the place to its right.
4.NBT.A.2 Read and write multidigit whole numbers using baseten numerals, number names, and expanded form. Compare two multidigit numbers based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.
4.NBT.A.3 Use place value understanding to round multidigit whole numbers to any place.
4.NBT.B.4 Fluently add and subtract multidigit whole numbers using the standard algorithm.
4.OA.B.4 Gain familiarity with factors and multiples. Find all factor pairs for a whole number in the range 1100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1100 is a multiple of a given onedigit number. Determine whether a given whole number in the range 1100 is prime or composite.
