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.

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

> 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

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.

- ✗ 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.

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
