topic 1 | lesson 2

Explanation:

To solve this problem, we need to count the dots in each set of boxes and circle the one with 2 dots (as per the directions, though let's analyze each part):

Problem 1:

• First box: Left is empty, right has 3 dots.
• Second box: Left has 2 dots, right has 1 dot (total 3? Wait, no, count dots in each box? Wait, the directions say "count the dots on each dot tile" (each tile is a box). Wait, maybe each tile (box) has dots, and we need to find which tile (box) in each row has 2 dots? Wait, the "Another Look!" shows tiles with 1, 2, 3 dots? Wait, first "Another Look" tile 1: left has 1, right 0 (total 1). Tile 2: left has 2, right 0 (total 2). Tile 3: left 1, right 1 (total 2? Wait no, first tile: 1 dot, second: 2 dots, third: 2 dots? Wait maybe the task is to circle the tile with 2 dots in each row.

Let's re-express:

Row 1 (Problem 1):

• Tile 1: Left empty, right has 3 dots (total 3)
• Tile 2: Left has 2 dots, right has 1 dot? Wait no, each tile is a box. Wait, maybe each tile is a box, and we count dots in each box. So:
• First box (tile) in row 1: right box has 3 dots (left empty) → 3 dots
• Second box: left has 2 dots, right has 1 dot? No, each box is separate. Wait, the "Another Look" has three tiles: first tile (left box 1 dot, right 0), second (left 2 dots, right 0), third (left 1, right 1). So maybe the task is to find the tile with 2 dots in each row.

Row 1 (Problem 1) tiles:

• Tile 1: right box has 3 dots → 3
• Tile 2: left box has 2 dots, right has 1? No, each box is a tile? Wait, maybe each tile is a pair of boxes, and we count total dots. Wait, "count the dots on each dot tile" – each tile is a pair of boxes. So:

• Tile 1 (row 1): left box 0, right box 3 → total 3
• Tile 2: left box 2, right box 1 → total 3
• Tile 3: left box 2, right box 0 → total 2

Ah, so tile 3 in row 1 has 2 dots. So circle tile 3.

Row 2 (Problem 2) tiles:

• Tile 1: left 0, right 1 → total 1
• Tile 2: left 2, right 0 → total 2
• Tile 3: left 1, right 0 → total 1

So tile 2 in row 2 has 2 dots. Circle tile 2.

Row 3 (Problem 3) tiles:

• Tile 1: left 1, right 1 → total 2
• Tile 2: left 2, right 1 → total 3
• Tile 3: left 2, right 0 → total 2

Wait, tile 1: 1 + 1 = 2; tile 3: 2 + 0 = 2. Wait, maybe the "2 dots" can be in different arrangements (as per the title "Recognize 1, 2, and 3 in Different Arrangements"). So tile 1 (1+1) and tile 3 (2+0) both have 2 dots? But maybe the task is to circle the one with 2 dots. Wait, tile 1: left 1, right 1 (total 2); tile 3: left 2, right 0 (total 2). But maybe the intended is tile 1? Wait, no, let's check the directions again: "draw a circle around the dot tile with 2 dots".

So:

Step 1: Analyze Row 1

• Tile 1: 0 + 3 = 3 dots
• Tile 2: 2 + 1 = 3 dots
• Tile 3: 2 + 0 = 2 dots → Circle Tile 3.

Step 2: Analyze Row 2

• Tile 1: 0 + 1 = 1 dot
• Tile 2: 2 + 0 = 2 dots → Circle Tile 2.
• Tile 3: 1 + 0 = 1 dot

Step 3: Analyze Row 3

• Tile 1: 1 + 1 = 2 dots → Circle Tile 1.
• Tile 2: 2 + 1 = 3 dots
• Tile 3: 2 + 0 = 2 dots → Also 2, but maybe tile 1 is the intended (since 1+1 is another arrangement).

So the circled tiles are:

1. Third tile in row 1.
2. Second tile in row 2.
3. First tile in row 3.

Answer:

To solve this problem, we need to count the dots in each set of boxes and circle the one with 2 dots (as per the directions, though let's analyze each part):

Problem 1:

• First box: Left is empty, right has 3 dots.
• Second box: Left has 2 dots, right has 1 dot (total 3? Wait, no, count dots in each box? Wait, the directions say "count the dots on each dot tile" (each tile is a box). Wait, maybe each tile (box) has dots, and we need to find which tile (box) in each row has 2 dots? Wait, the "Another Look!" shows tiles with 1, 2, 3 dots? Wait, first "Another Look" tile 1: left has 1, right 0 (total 1). Tile 2: left has 2, right 0 (total 2). Tile 3: left 1, right 1 (total 2? Wait no, first tile: 1 dot, second: 2 dots, third: 2 dots? Wait maybe the task is to circle the tile with 2 dots in each row.

Let's re-express:

Row 1 (Problem 1):

• Tile 1: Left empty, right has 3 dots (total 3)
• Tile 2: Left has 2 dots, right has 1 dot? Wait no, each tile is a box. Wait, maybe each tile is a box, and we count dots in each box. So:
• First box (tile) in row 1: right box has 3 dots (left empty) → 3 dots
• Second box: left has 2 dots, right has 1 dot? No, each box is separate. Wait, the "Another Look" has three tiles: first tile (left box 1 dot, right 0), second (left 2 dots, right 0), third (left 1, right 1). So maybe the task is to find the tile with 2 dots in each row.

Row 1 (Problem 1) tiles:

• Tile 1: right box has 3 dots → 3
• Tile 2: left box has 2 dots, right has 1? No, each box is a tile? Wait, maybe each tile is a pair of boxes, and we count total dots. Wait, "count the dots on each dot tile" – each tile is a pair of boxes. So:

• Tile 1 (row 1): left box 0, right box 3 → total 3
• Tile 2: left box 2, right box 1 → total 3
• Tile 3: left box 2, right box 0 → total 2

Ah, so tile 3 in row 1 has 2 dots. So circle tile 3.

Row 2 (Problem 2) tiles:

• Tile 1: left 0, right 1 → total 1
• Tile 2: left 2, right 0 → total 2
• Tile 3: left 1, right 0 → total 1

So tile 2 in row 2 has 2 dots. Circle tile 2.

Row 3 (Problem 3) tiles:

• Tile 1: left 1, right 1 → total 2
• Tile 2: left 2, right 1 → total 3
• Tile 3: left 2, right 0 → total 2

Wait, tile 1: 1 + 1 = 2; tile 3: 2 + 0 = 2. Wait, maybe the "2 dots" can be in different arrangements (as per the title "Recognize 1, 2, and 3 in Different Arrangements"). So tile 1 (1+1) and tile 3 (2+0) both have 2 dots? But maybe the task is to circle the one with 2 dots. Wait, tile 1: left 1, right 1 (total 2); tile 3: left 2, right 0 (total 2). But maybe the intended is tile 1? Wait, no, let's check the directions again: "draw a circle around the dot tile with 2 dots".

So:

Step 1: Analyze Row 1

• Tile 1: 0 + 3 = 3 dots
• Tile 2: 2 + 1 = 3 dots
• Tile 3: 2 + 0 = 2 dots → Circle Tile 3.

Step 2: Analyze Row 2

• Tile 1: 0 + 1 = 1 dot
• Tile 2: 2 + 0 = 2 dots → Circle Tile 2.
• Tile 3: 1 + 0 = 1 dot

Step 3: Analyze Row 3

• Tile 1: 1 + 1 = 2 dots → Circle Tile 1.
• Tile 2: 2 + 1 = 3 dots
• Tile 3: 2 + 0 = 2 dots → Also 2, but maybe tile 1 is the intended (since 1+1 is another arrangement).

So the circled tiles are:

1. Third tile in row 1.
2. Second tile in row 2.
3. First tile in row 3.
