iii How to Take the Zing out of Zingers!

How to Take the Zing Out of Zingers!You can solve Zingers! Follow these steps . They will help you do better on test problems .

STEP 1 READ and UNDERSTAND Read the problem carefully .

READ and UNDERSTAND Read the problem carefully. 45% of students missed it!

1. There were 6 | 8 | 4 students. Each student

collected 6 | 8 | 4 pictures.

2. How many pictures were on each poster?

3. The correct equation shows a way to find the total number

To make posters, 6 students each collected 8 pictures of animals. The students put 4 animal pictures on each poster they made. Which equation

A 6 + 8 + 4 = 18 C 6 × 8 × 4 = 192

B 6 × 8 ÷ 4 = 12 D 6 + 8 − 4 = 10STAAR Grade 3 2016 #24

1. Look at the numbered questions below the boxed problem . How can these questions help you solve the problem?

If you are not sure how to solve this problem, that’s OK! Go on to the next section . If you do know how, solve the problem now . But don’t stop here! Keep reading . You may learn another method .

STEP 2 PLAN and SOLVE Read how two students solved the problem .

PLAN and SOLVE Read what each student thinks.

Daisy thinks . . .

Each student collected 8 pictures, so that’s 6 × 8 = 48 pictures in all. Then they put 4 pictures on each poster.

4 48 _ ⟌

My choice is B.

Carla thinks . . .

First I would multiply 6 by 8 to find how many pictures they collected. So I can eliminate A and D.

Then I would multiply by 4 because each poster has 4 pictures.

My choice is C.

4. Daisy divides | multiplies 5. Carla is | is not correct when

2. These two students’ answers are different | the same .

So, it is | is not possible for both students to be right .

As you read what each student thinks, try to find mistakes . Then you won’t make the same mistakes yourself .Sampler

iv How to Take the Zing out of Zingers!

STEP 3 LOOK BACK What did you learn by seeing how other students solved the problem?

LOOK BACK Answer each question.

6. Tell why Carla’s answer is not correct.

Did you learn a new way to solve the problem? Knowing different ways to solve problems helps you on the test .

STEP 4 GUIDED PRACTICE Now solve a similar problem . The steps below the problem can help you solve it .

GUIDED PRACTICE Read the problem carefully.

10. On parents’ night, there were as many chairs.

That means you would multiply | divide the current

number by to find the number on parents’ night.

11. The correct answer is F | G | H | J .

A classroom currently contains 6 rows of chairs with 5 chairs per row. On parents’ night the classroom had twice as many chairs.

classroom on parents’ night?

F 6 + 5 + 2 = H 6 ´ 5 ¸ 2 =

G 6 ´ 5 ´ 2 = J 6 + 5 ´ 2 = STAAR Grade 3 2017 #21

STEP 5 INDEPENDENT PRACTICE Finally, try these problems on your own . Use everything you have learned . You can do it!

INDEPENDENT PRACTICE Solve the problem.

12. Mario makes a poster for science class. First he draws 4 rows of 9 seashells each. Then he circles equal groups of shells. In all, he draws 6 circles. Fill in the number sentence to show one way to find the number of shells in each circle.

4 ´ 6 = 6

Solving STAAR problems takes time . Work carefully, and write neatly . If you get a wrong answer, look at your work . Try to find your mistake . If you understand a mistake, you may not make it again .

10 Grade 3 Mathematics STAAR Zingers Solving the Most-Missed STAAR Test Items

3.4A Solve with fluency one-step and two-step problems involving addition and subtraction within 1,000 using strategies based on place value, properties of operations, and the relationship between addition and subtraction.


1. Mr. Thompson sold 247 meals on and 516

meals on .

2. You want to find the difference | total of the numbers of meals sold on these two days.


Dalila thinks . . .

The word “difference” means subtract. So A can’t be right, because 763 is bigger than both 247 and 516.

516 is close to 500 and 247 is close to 250. The difference is about 500 − 250 = 250.

Check: 2 1 4 1 7

✓

Keenan thinks . . .

I’ll start at 247 and add on.

+100 +100

247 347 447 547

+100

Adding on 200 makes 447. That’s too small. But adding on 300 makes 547, and that’s too big. The right answer must be between 200 and 300.

My choice is D.

3. Dalila adds | subtracts to find the answer. Then she

adds | subtracts to check.

4. Keenan adds | subtracts and

compares the result to .

5. Why does Keenan choose D?

Mr. Thompson sold 247 meals on Tuesday at his restaurant. He sold 516 meals on Wednesday. What is the difference between the numbers of meals Mr. Thompson sold on these two days? STAAR Grade 3 2016 #46

10. The total amount she has now equals the sum you found

in #9 plus | minus $137.

11. The correct answer is . Write this number in the grid and fill in the bubbles.

12. The table shows the numbers of pieces in four puzzles. Derek put together the two puzzles that had the greatest numbers of pieces. What is the total number of pieces in these two puzzles?

Adyssen started with $87 in her bank account. She put $213 into her account last week and another $137 this week.

What is the total amount Adyssen now has in her bank account?
