Overview Strand(s): Numbers & Operations, Geometry & Measurement Unit 1: Ordering & Comparing, Rounding, and Adding & Subtracting Numbers to 100,000 Approximate Duration of Study: 7 FULL Weeks of Instruction MNSS Knowledge Skills Fluency Core Knowledge Number to 100,000 3.1.1.1 Addition increases a value, subtraction decreases a value There is a relationship between addition and subtraction facts. Numbers can be represented in a variety of ways including: o Numerals, expressions with operations, words, pictures, number lines, and manipulatives. Demonstrate fluency with basic addition facts and related subtraction facts. Read, write and represent (in digits and words) whole numbers up to 100,000 using a variety of methods. Review dozen, half-dozen and pair. Place Value 3.1.1.2 3.1.1.3 Rounding, Estimating and Comparing 3.1.1.4 3.1.1.5 A digit represents a place value in a whole number. o The digit 4 in 4,327 has a value of 4,000 because 4,000 + 300 + 20 + 7 = 4,327 Non-exact values can be used to make predictions/decisions/confirm if an answer is reasonable or not. o $4,357 can be rounded to $4,400 (hundreds place) to estimate the amount of savings needed to make a $4,357purchase. Place value can be used to make comparisons and order numbers from least to greatest and vice versa. o Greater than: > (e.g. 6 > 2) o Less than: < (e.g. 2 < 6) o Equal to: = (e.g. 6 = 6) Recognize and use place value to describe and write whole numbers between 1000 and 100,000 in terms of ten thousands, thousands, hundreds, tens and ones. Write numbers in expanded form. Find 10,000, 1000, 100 more or less than a given 4- or 5-digit number. Round a number to the nearest 10,000, 1000, 100, 10. Round numbers to estimate sums and differences. Use a number line to round numbers to the nearest tens, hundreds or thousands. Compare whole numbers up to 100,000. Order whole numbers up to 100,000. Use a number line to compare and order numbers. Unit 1 Page 3
Place Value: Add & Subtract Place value is used to add and subtract multi-digit numbers. o Algorithm: add/subtract from right to left (i.e. ones, tens, hundreds, etc.). Add and subtract multi-digit numbers using place value as a guide. Add and subtract with and without regrouping up to 10,000. 3.1.2.1 Addition and subtraction are inverse (opposite) operations. Use addition to check subtraction and vice versa. Addition & Subtract in the Real World 3.1.2.2 Multiplication 3.1.2.3 Addition and subtraction of whole numbers can be applied to real-world situations. Multiple strategies can be applied to assess the reasonableness of results. Multiplication can be represented using: o Repeated addition o Equal-sized groups o Arrays o Area models o Equal jumps on a number line o Skip counting Use addition and subtraction of whole numbers to solve real-world problems. Solve two-step word problems. Make sense of solutions using: o The relationship between addition and subtraction. o Technology o Context of the problem Use various methods to represent multiplication facts. Count by twos, threes, fives and tens. Count by tens from any given number. Use a number line to represent multiplication. Mentally multiply by 10, 100, and 1,000. Estimate a product. In order for a number to be even the last digit must be a 0, 2, 4, 6, or 8. Even numbers can be split into groups, with each group containing the same amount of numbers, objects, symbols, etc. In order for a number to be odd the last digit must be a 1, 3, 5, 7, or 9. Odd numbers can be split into groups, with each group containing the same amount (of numbers, objects, symbols, etc.) but always having an unequal group remaining. o A group of 25 students can be split into 5 groups of 5 but 25 is not an even number because it does not end in 0, 2, 4, 6, or 8. Review even and odd numbers. Determine if a number is even or odd. There is a relationship between multiplication and division. Multiplication and division are inverse operations. o 9 x 6 = 54; 6 x 9 = 54, 54 9 = 6; 54 6 = 9 Use fact families to illustrate the relation between multiplication and division. Page 4 Unit 1
Properties of Multiplication 3.1.2.5 Place value, equality and properties of addition/multiplication are used to multiply two- and three-digit numbers by a one-digit number. Mental strategies, partial products, standard algorithms, and the commutative, associative, and distributive properties can be used to multiply two- and three-digit numbers by a single digit number. o Commutative: 23 x 2 = 2 x 23 o Associative: (12 x 2) x 4 = 12 x (2 x 4) o Distributive: 12 x 2 = 2(10 + 2) o Partial Products: 345 x 2 = 300 x 2 = 600 40 x 2 = 80 5 x 2 = + 10 690 Use strategies to multiply two- and three-digit numbers by a onedigit number, with and without regrouping. (Strategies assist with creating an easier problem to solve.) Multiplication in the Real World 3.1.2.4 Multiplication can be applied to real-world situations. Use multiplication to solve real-world problems. o There are 9 tables and each table can seat 4 people. How many people can be seated altogether?

Basic multiplication and division facts can be used to solve for the unknown. Identify and apply the rule in an input-output table to continue the pattern or solve for missing values. Create an input-output table using a given rule. Use a variable to represent the unknown value in a number sentence based on real world situation. o The number sentence 8 m = 24 could be represented by the question How much did each ticket to a play cost if 8 tickets totaled $24?

Fractions: Numerator and Denominator 3.1.3.1 Fractions: Representation & Measurement 3.1.3.2 Fractions can be represented by words and symbols. Fractions represent a part of a whole. The numerator represents the part (top of fraction) and the denominator represents the whole (bottom of fraction). A mixed number consists of a whole part and fractional part. An improper fraction is a fraction whose numerator is greater than the denominator. A mixed number can be converted to an improper fraction and vice versa. Fractions are used to represent: o Parts of a whole o Parts of a set o Points on a number line o Distances on a number line Unit 2 Recognize, read and write fractions up to 1 10. o Parts of a shape ( 3 of a pie) 4 o Parts of a set ( 3 out of 4 people) o Measurements ( 3 of an inch) 4 Recognize fractions whose denominators is 100.

In unit fractions, the larger the denominator, the smaller the value. In fractions with like denominators, the larger the numerator, the larger the value. Decimals represent parts of whole numbers. A value less than 1 is represented by using a decimal. Different coin combinations can sum to the same amount of money. o E.g. 10 pennies and 4 dimes = 2 quarters = 4 nickels and 3 dimes. Data can be represented by: o Frequency table o Bar Graph o Picture Graph o Number Line Plot Scale measures quantity. o The scale is marked on the x- or y-axis. The scale of a graph determines how it is read. o On a bar graph, each line or space may represent more than one unit. Appropriate title, labels and units must be used. Explain that the size of a fraction depends on the size of the whole. (Choose which fraction represents the smaller/larger amount even though the fractions may be the same.) o One-half of a small pizza is smaller than one-half of a large pizza, but both represent one-half. Order and compare unit fractions and fractions with like denominators using the signs <, > and =. Read and write decimals to the hundredths. o Make change, up to one dollar, using as few coins as possible and in more than one way. o Write amounts of money using $ and signs, and the decimal point. o Add and subtract amounts of money. o Multiply and divide amounts of money by small whole numbers. Collect data. Display and interpret data Create and interpret bar graphs. Measuring Time A digital or analog clock can be used to measure time. o Hours, minutes, seconds.
