Here are the solutions to the problems on the worksheet, broken down by section.

Left Page: Grams & Kilograms

1. How many more grams does each student need to make 1 kg?
*Remember: 1 kilogram (kg) = 1,000 grams (g). To find the answer, subtract the weight they have from 1,000.*

* Boy with 500g: $1,000 - 500 = \mathbf{500}$ g
* Girl with 400g: $1,000 - 400 = \mathbf{600}$ g
* Boy with 900g: $1,000 - 900 = \mathbf{100}$ g
* Girl with 250g: $1,000 - 250 = \mathbf{750}$ g

2. For each box, circle the 3 weights that combine to make 1 kg (1,000 g).

* Top Box (Apple, Banana, Watermelon):
* $250 + 100 + 650 = 1,000$
* Circle: Apple (250g), Banana (100g), and Watermelon (650g).

* Middle Box (Pepper, Grapes, Pumpkin):
* $50 + 750 + 200 = 1,000$
* Circle: Pepper (50g), Grapes (750g), and Pumpkin (200g).

* Bottom Box (Donut, Candy, Fries):
* $70 + 80 + 850 = 1,000$
* Circle: Donut (70g), Candy (80g), and Fries (850g).

3. Draw the grocery items below on the number line.
*The scale goes from 0g to 500g. The middle mark is 250g.*

* Bread (700g): This is heavier than 500g, so it goes to the right of the 500g mark.
* Can (300g): This is past the middle (250g) but before 500g. Draw it between the middle and the end.
* Flower (400g): This is close to the 500g mark. Draw it near the right end, but not quite at 500g.

1. Circle the heaviest item in each group.

* Row 1: Teddy Bear, Soccer Ball, Bowling Ball, Camera.
* Answer: Bowling Ball (It is made of heavy material and is dense).
* Row 2: Peanut, Chicken Leg, Taco, Loaf of Bread.
* Answer: Loaf of Bread (A whole loaf is heavier than a single leg, taco, or peanut).
* Row 3: Caterpillar, Butterfly, Ladybug, Frog.
* Answer: Frog (Amphibians are generally much heavier than insects).

2. Number the following items from lightest (1) to heaviest (5).

1. Pizza Slice (30g) - Lightest
2. Hamburger (175g)
3. Milk Carton (1000g) *(Note: 1000g = 1kg)*
4. Jar of Candy (1.5kg) *(Note: 1.5kg = 1500g)*
5. Basket of Fruit (2kg) *(Note: 2kg = 2000g)* - Heaviest

Order: Pizza (1), Hamburger (2), Milk (3), Jar (4), Basket (5).

3. Draw the correct scale weights to balance the scales.
*To balance the scale, the weight on the empty side must equal the weight on the full side.*

* Scale 1 (Left has 2.5kg): Draw a weight labeled 2.5kg (or two weights: 2kg and 500g) on the right side.
* Scale 2 (Left has 75g): Draw a weight labeled 75g on the right side.
* Scale 3 (Right has 180g): Draw a weight labeled 180g on the left side.
* Scale 4 (Right has 1.5kg): Draw weights on the left that add up to 1.5kg. You can draw one big weight labeled 1.5kg, or three smaller ones labeled 1kg, 250g, and 250g.

Final Answer:
Left Page:
1. 500g, 600g, 100g, 750g
2. Box 1: 250+100+650; Box 2: 50+750+200; Box 3: 70+80+850
3. Bread (>500g), Can (~300g), Flower (~400g)

Right Page:
1. Heaviest items: Bowling Ball, Loaf of Bread, Frog
2. Order (Lightest to Heaviest): Pizza(1), Hamburger(2), Milk(3), Jar(4), Basket(5)
3. Balance weights: Right side needs 2.5kg; Right side needs 75g; Left side needs 180g; Left side needs 1.5kg total.
