Solving Word Problems Core Skills 1 1.OA.1: Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.

A plus sign (+) in an addition sentence indicates that the numbers are added, joined, or combined together.

2+3=5

4+5=8

THINK Use drawings to represent the number sentence.

Counting the total number of dots, we can see that there are 5 dots. Therefore, the addition sentence is CORRECT.

Counting the total number of dots, we can see that there are 9 dots. Therefore, the addition sentence is NOT CORRECT.

DIRECTIONS: Place a check mark () in the box if the statement is CORRECT and an X in the box () if the addition sentence is NOT CORRECT. Use scrap paper to make your dots. 1.

Applying Properties of Addition and Subtraction Core Skills 1 1.OA.3: Apply properties of operations as strategies to add and subtract.

A fact family is a collection of related addition and subtraction facts made from the same set of numbers

3–2=1 3–1=2

1+2=3 2+1=3

THINK Look at the 2 addition sentences. Notice how they add up to the same sum. Also, notice also how changing the order of the addends still result in the same sum. 1+2=3 2+1=3 Look at the 2 subtraction sentences. Notice how they “undo” the addition sentences. 1+2=3 → 3–2=1 2+1=3 → 3–1=2 Since the 3 numbers (1, 2, 3) are related to each other as defined by the 4 equations, they belong to the same fact family. DIRECTIONS: Circle the equation that does not belong to the same fact family.

Using Strategies for Subtracting Core Skills 1 1.OA.4: Understand subtraction as an unknown-addend problem.

Addition and subtraction are related operations. The relationship between addition and subtraction is inverse.

6+?=9

? + 7 = 11

THINK If we look at the addition sentence, we can read it as “what must be added to 6 to get 9?”. Now, consider the related subtraction fact: 9–6=3 Notice how subtraction “cancels” the addition operation. Thus, the missing number is 3. So, let us try: 6+3=9 We find the answer to be CORRECT.

THINK If we look at the addition sentence, we can read it as “what must be added to 7 to get 11?”. Now, consider the related subtraction fact: 11 – 7 = 4 Notice how subtraction “cancels” the addition operation? Thus, the missing number is 4. So, let us try: 4 + 7 = 11 We find the answer to be CORRECT.

DIRECTIONS: Circle the number that makes the addition sentence CORRECT. 1.

Addition and subtraction are related operations. The relationship between addition and subtraction is inverse.

6 + 1 + ? = 10

?–1−4=3

THINK If we add the first 2 numbers together, our equation becomes: 7 + ? = 10 Now, consider the related subtraction fact: 10 – 7 = 3 Because we know now that subtraction “cancels” addition, we know that the missing number is 3. Let us try! 6 + 1 + 3 = 7 + 3 = 10

THINK If we subtract the last 2 numbers together, our equation becomes: ?–5=3 Now, consider the related addition fact: 3+5=8 Because we know now that addition “cancels” subtraction, we know that the missing number is 8. Let us try! 8–1–4=8–5=3

Comparing Numbers Core Skills 1 1.NBT.3: Compare two two-digit numbers based on meanings of the tens and ones digits, recording the results of comparisons with the symbols >, =, and <.

The greater than sign (>) indicates that the left number has a bigger or larger value than the right number. The less than sign (<) indicates that the left number has a smaller or lesser value than the right number. The equal sign (=) indicates that the 2 numbers have the same value.

48 > 56

61 > 26

THINK When comparing 2 numbers, we always start by comparing the digits in the higher place value.

Comparing the tens digit of the 2 numbers, we can see that 6 has a bigger value than 2. Therefore, it is CORRECT.

Comparing the tens digit of the 2 numbers, we can see that 4 has a smaller value than 5. Therefore, it is INCORRECT.

61 > 26

48 < 56

DIRECTIONS: Compare the 2 numbers. Place a greater than sign (>), a less than sign (<), or an equal sign (=) to make the statement CORRECT.

Solving Two-Digit Addition Core Skills 1 1.NBT.4: Add within 100, including adding a two-digit number and a one-digit number, and adding a two-digit number and a multiple of 10. Understand that in adding two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten.

A plus sign (+) in an addition sentence indicates that the numbers are added, joined, or combined together.

23 + 5 = 28

41 + 20 = 60

THINK When adding 2-digit numbers to 1-digit numbers, we need to add the ones digits before adding the tens digit. 23 3 + 5 = 8 (ones) + 5 2 + 0 = 2 (tens) 28 Therefore, the addition sentence is CORRECT.

THINK When adding two 2-digit numbers, we need to add the ones digits before adding the tens digit. 41 1 + 0 = 1 (ones) + 20 4 + 2 = 6 (tens) 61 Therefore, the addition sentence is NOT CORRECT.

DIRECTIONS: Place a check mark () inside the box if the addition sentence is CORRECT and an X () if the addition sentence is NOT CORRECT. 1.

Calculating 10 more and 10 less Core Skills 1 1.NBT.5: Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used.

When adding or subtracting 10 to or from a two-digit number, all you have to do is add to or subtract from the tens digit.

45 + 10 = 55

78 − 10 = 68

THINK

When adding two 2-digit numbers, we need to add the ones digits first. But adding 0 to any number does not change the number. Therefore, if you add 10 to a two-digit number, all you have to do is add the tens digit and copy the ones digit.

When subtracting two 2-digit numbers, we need to subtract the ones digits first. But subtracting 0 from any number does not change the number. Therefore, if you subtract 10 from a two-digit number, all you have to do is subtract the tens digit and copy the ones digit. 78 (Use the same ones) − 10 7 − 1 = 6 (tens) 68

Solving Two-Digit Subtraction Core Skills 1 1.NBT.6: Subtract multiples of 10 in the range 10-90 from multiples of 10 in the range 10-90 (positive or zero differences), 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.

When subtracting multiples of 10 from multiples of 10, a great practice is to subtract the tens digit, and place a 0 in the ones place.

THINK When subtracting two 2-digit numbers, we need to subtract the ones digits first, but subtracting 0 from 0 is always 0. Hence, if you subtract multiples of 10 from multiples of 10, all you have to do is subtract the tens digit, and place a 0 in the ones digit.

70 − 20 = 50

80 − 40 = 40

70 (Put a 0 in the ones digit) − 20 7 − 2 = 5 (tens) 50

80 − 40 40

(Put a 0 in the ones digit) 8 − 4 = 4 (tens)

DIRECTIONS: Write the CORRECT answer to the subtraction sentence.

108

70 − 20 = ___

60 − 40 = ___

20 − 10 = ___

Length is the measurement of an object from one end to another.

THINK When measuring an object using shorter objects, lay down the object on a flat surface, and lay multiple copies of a shorter object below it so they run from end-to-end. The length of the object will equal to the number of shorter objects that span it with NO GAPS or OVERLAPS. Look at the branch. Count the number of paper clips that span its length.
