Count backwards by 100. What are the next three numbers? 900, 800, 700, _____, _____, _____ Ralph has 957 race car stickers. He gave 10 to Ken. He gave 100 to Matt. How many stickers does Ralph have left? 747 stickers b. 947 stickers; c. 946 stickers d. 847 stickers

I can… 25, 30, , 40, __, __ Skip count by 2’s. 12, __, __, __, -tell what it means to skip count. Skip counting is counting objects in equal groups of two or more Example: 2, 4, 6, 8, 10, 12, 14 or 3, 6, 9, 12, 15, 18 or 10, 15, 20, 30, 35, 40 -skip count by 2’s, forward, backward, and beginning at any number. Examples 4, 6, __, 10, __, __, (answers 8, 12, 14) 56, 58, __, __, ___, (answers 60, 62, 64) 102, 100, __, __, __ (answers 98, 96, 94) -skip count by 5’s forward, backward, and beginning at any number. Examples: 15, 20, __, 30, __, __, (answers 25, 35, 40) 75, 80, __, __, ___, (answers 85, 90, 95) 110, 105, __, __, __ (answers 100, 95, 90) -tell what it means to be in equal groups. An equal group has the same number of objects in each group. -put objects in equal groups. --identify an even number. Numbers that end with a 0, 2, 4, 6, or 8 are even. -identify an odd number. Numbers that end with a 1, 3, 5, 7, or 9 are odd. -explain how to tell if a number is even or odd. Even numbers pair up into equal groups. Odd numbers do not pair up equally and have one left over. Skip count by 2’s. 12, __, __, __, 14, 16, 18 Skip count. Find the missing numbers.  25, 30, , 40, __, __ Which set of pictures shows an odd amount? How do you know it is odd?

I can… -show that any even number can be written as a sum -compare numbers to 1,000. -compare 3-digit numbers using <, >, and =. Use logical reasoning and basic information from this study guide to reason through mathematical problems. Example: Why does an even addend and an odd addend always make an odd sum? -show that any even number can be written as a sum of two equal addends. Example: 8 = 4 + 4 16 = 8 + 8 5 + 5 = 10 -solve math word (story) problems. Mrs. Lovely has 14 gumballs. She wants to split them between her two sisters. How many gumballs will she give each sister? Answer: 14 = 7 + 7

compare: look at objects, shapes, or numbers and see how they are alike or different. digit: a symbol used to write numbers. The ten digits are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. equal groups: each group has the same number of objects equal to: the same as 875 = 800 + 70 + 5 765 = 765 even: a number of objects that can be counted by 2s. Numbers that end with 0, 2, 4, 6, 8. expanded form: the representation of a number as a sum that shows the value of each digit. 536 is written as 500 + 30 + 6. greater than: > more than 765 > 763 hundreds: The numbers in the range of 100-999. A place value of a number. 853 8 is in the hundreds place less than: < fewer than 763 < 765 odd: a number of objects that has 1 left over when counted by 2s. Numbers that end with 1, 3, 5, 7, or 9. ones: the numbers in the range of 0-9. A place value of a number. 853 3 is in the ones place place value: tells the value of a digit in a number. repeated addition: to use the same addend over and over skip count: count objects in equal groups of two or more tens: the numbers in the range of 10-99. A place value of a number. 853 5 is in the tens place thousand: the numbers in the range of 1,000-9,999. A place value of a number. 1,000 1 is in the thousands place
