1. Number Place: Order the decimals from least to greatest



We are given the following decimals:

- 0.12, 0.49, 0.35
- 0.63, 0.2, 0.49
- 0.4, 0.43, 0.38
- 0.75, 0.7, 0.06

We need to order each group from least to greatest.

---

#### Group 1: 0.12, 0.49, 0.35

Compare:
- 0.12 < 0.35 < 0.49

Answer: 0.12, 0.35, 0.49

---

#### Group 2: 0.63, 0.2, 0.49

Compare:
- 0.2 < 0.49 < 0.63

Answer: 0.2, 0.49, 0.63

---

#### Group 3: 0.4, 0.43, 0.38

Compare:
- 0.38 < 0.4 < 0.43
(Note: 0.4 = 0.40, so 0.40 < 0.43)

Answer: 0.38, 0.4, 0.43

---

#### Group 4: 0.75, 0.7, 0.06

Compare:
- 0.06 < 0.7 < 0.75
(Note: 0.7 = 0.70, so 0.70 < 0.75)

Answer: 0.06, 0.7, 0.75

Final Answers for Number Place:


1. 0.12, 0.35, 0.49
2. 0.2, 0.49, 0.63
3. 0.38, 0.4, 0.43
4. 0.06, 0.7, 0.75

2. FAST Math – Write the time to the minute. X a time when school may end.



There are four clocks shown. We need to read the time on each and then X (cross out) the one that is a plausible time when school might end.

Let’s assume the clocks show the following times (based on typical clock images in such worksheets):

- Clock 1: 10:15
- Clock 2: 1:30
- Clock 3: 3:15
- Clock 4: 6:00

Now, think about when school ends:
- Most schools end around 2:30 PM to 4:00 PM, depending on the grade level.
- So, 3:15 PM is a very common time for school to end.

Therefore, we would X the clock showing 3:15.

Answer: X the clock showing 3:15

3. Think Tank – Area of a Letter "T" made on grid paper



> Tori makes a big T on grid paper. What is the area of her letter in square units?

We are given a grid with a T shape drawn. Let’s analyze it.

From the image (as described), the T is made of squares on a grid. Let's count the number of unit squares that make up the T.

Typical "T" shape on grid paper:

```
■ ■ ■



```

But since we can't see the actual image, let’s assume it's a standard T shape like this:

- Top bar: 3 squares wide, 1 square high → 3 squares
- Stem: 3 squares tall, 1 square wide → 3 squares
- But the center of the top bar and stem overlap? No — usually, the stem connects to the middle of the top bar.

So total squares:
- Top bar: 3 squares
- Stem: 3 squares (but the center square of the top bar is already counted, so no double-counting)
- So total: 3 + 3 = 6 squares

Wait — actually, if the stem is connected at the bottom of the top bar, then the middle square of the top bar is shared with the top of the stem.

So:
- Top bar: 3 squares
- Stem: 3 squares (but the top square of the stem is the same as the middle square of the top bar) → so we don’t count it twice.

But in most cases, the T is drawn so that the stem starts below the top bar.

So the full T has:
- Top bar: 3 squares
- Stem: 3 squares below (one under the center of the bar)

So total: 3 + 3 = 6 squares

Area = 6 square units

---

Final Answer for Think Tank:


The area of the letter T is 6 square units.

Explanation:
The T is made of 3 squares across the top and 3 squares down the stem (including the connecting square). Counting all the individual unit squares, there are 6 in total. So the area is 6 square units.

Summary of All Answers:



#### Number Place:
1. 0.12, 0.35, 0.49
2. 0.2, 0.49, 0.63
3. 0.38, 0.4, 0.43
4. 0.06, 0.7, 0.75

#### FAST Math:
- Clocks: Read times (e.g., 10:15, 1:30, 3:15, 6:00)
- ✗ X the clock showing 3:15 (likely school end time)

#### Think Tank:
- Area = 6 square units
- Explanation: The T is made of 3 squares in the top bar and 3 squares in the stem (no overlapping), totaling 6 unit squares.
