Grade 3 Daily Math Practice Worksheet - Day 40

I'll solve each problem step by step, checking my work carefully.

Problem 1: 256 × 0 = ?
- Any number multiplied by 0 equals 0
- Answer: 0

Problem 2: Write the number that comes after 7895
- After 7895 comes 7896
- Answer: 7896

Problem 3: Write the date a week before 15/7/07
- A week is 7 days
- 15 - 7 = 8
- So it's 8/7/07
- Answer: 8/7/07

Problem 4: How many days are there in two years?
- One year has 365 days (not counting leap years)
- Two years: 365 × 2 = 730 days
- Answer: 730 days

Problem 5: The time is 9:10 now. What will the time be after 20 minutes?
- 9:10 + 20 minutes = 9:30
- Answer: 9:30

Problem 6: How many edges are in a cylinder?
- A cylinder has 2 circular edges (top and bottom) and 1 curved edge around the side
- Total: 2 + 1 = 3 edges
- Answer: 3

Problem 7: Perimeter of the figure
Let me trace around the shape:
- Bottom: 6 cm
- Right side going up: 3 cm
- Top right horizontal: 3 cm
- Going down: 3 cm
- Middle horizontal: 3 cm
- Left side going up: 3 cm
- Top left horizontal: 3 cm
- Wait, let me look at this more carefully.

Looking at the L-shaped figure:
- Starting from bottom left, going clockwise:
- Bottom: 6 cm
- Right vertical: 3 cm
- Top right horizontal: 3 cm
- Down vertical: 3 cm
- Middle horizontal: 3 cm
- Left vertical: 3 cm
- Top horizontal: 3 cm

Actually, let me add all sides:
The perimeter goes around the entire outside:
6 + 3 + 3 + 3 + 3 + 3 + 3 = 24 cm

Wait, I need to be more careful. Let me count the segments:
- Bottom: 6 cm
- Right side: 3 cm
- Top right part: 3 cm
- Inner vertical: 3 cm
- Inner horizontal: 3 cm
- Left side: 3 cm
- Top left part: 3 cm

Total: 6 + 3 + 3 + 3 + 3 + 3 + 3 = 24 cm

Answer: 24 cm

Problem 8: How many faces are there in a sphere?
- A sphere has no flat faces
- It has 1 curved surface
- But in terms of "faces" as we usually count them, a sphere has 0 flat faces
- However, some might say 1 face (the curved surface)
- In elementary math, typically: 0 faces or 1 curved face
- Most commonly taught answer: 0 faces (no flat faces)

Actually, for grade 3 level, they likely want: 0 faces (since a sphere has no flat surfaces like other shapes)

Answer: 0

Problem 9: Odd number × odd number = ?
- When you multiply two odd numbers, you always get an odd number
- Examples: 3 × 5 = 15, 7 × 3 = 21
- Answer: odd number

Problem 10: What is the cost of 4 text messages at 25 cents each?
- 4 × 25 cents = 100 cents
- 100 cents = $1.00
- Answer: $1.00

Problem 11: What is the 8th letter of the alphabet?
- A(1), B(2), C(3), D(4), E(5), F(6), G(7), H(8)
- Answer: H

Problem 12: Compare 2/5 and 6/5
- Both have the same denominator (5)
- 2/5 means 2 parts out of 5
- 6/5 means 6 parts out of 5
- 2 < 6, so 2/5 < 6/5
- Answer: <

Problem 13: How many centimetres make up 7.5 m?
- 1 metre = 100 centimetres
- 7.5 m = 7.5 × 100 cm = 750 cm
- Looking at options:
- a. 75 m (this doesn't make sense)
- b. 750 cm ✓
- Answer: b. 750 cm

Problem 14: 49000 - 10000 = ?
- 49000 - 10000 = 39000
- Answer: 39000

Problem 15: Tick the two congruent shapes
- Congruent means same size and same shape
- Looking at the shapes: circle, triangle, circle, triangle
- The two circles are congruent (same shape and size)
- The two triangles appear to be different sizes
- Answer: The two circles (first and third shapes)

Problem 16: 400 + 200 + 30000 = ?
- First: 400 + 200 = 600
- Then: 600 + 30000 = 30600
- Answer: 30600

Problem 17: How many days are there in August?
- August has 31 days
- Answer: 31 days

Problem 18: Draw hands to show 6:15 am
- Hour hand: slightly past 6 (quarter way toward 7)
- Minute hand: pointing at 3 (which represents 15 minutes)
- This requires drawing, not a written answer

Problem 19: 1² = ?
- 1 squared means 1 × 1 = 1
- Answer: 1

Problem 20: Pattern: 1, x, 2, 1×, 3, ___
- Let me look at this pattern more carefully
- It seems to be: 1, __, 2, __, 3, __
- Or possibly: 1, x, 2, 1×, 3, ?
- Looking at the sequence: 1, x, 2, 1×, 3, ?
- Hmm, this is confusing. Let me re-read it.
- Actually looking at it again: "1, x, 2, 1×, 3, ___"
- This might mean: 1, _, 2, _, 3, _ where blanks are being filled
- Or it could be showing a multiplication pattern
- If it's 1, then something, then 2, then 1 times something, then 3...
- Actually, I think this shows: position 1 has value 1, position 2 is blank (x), position 3 has value 2, position 4 shows "1×", position 5 has value 3
- The pattern seems to be: 1, (blank), 2, (blank with 1×), 3, (blank)
- Following this: 1, ?, 2, ?, 3, ?
- The missing values would be: 1, 1, 2, 2, 3, 3? No that doesn't fit.
- Or maybe: the numbers increase by 1 every other position
- Position 1: 1, Position 3: 2, Position 5: 3
- So Position 6 should be... continuing the pattern
- Actually wait - if positions 1,3,5 are 1,2,3 then positions 2,4,6 might follow another pattern
- Position 2 is marked x, Position 4 shows 1×
- Hmm, "1×" might mean "1 times" or it could be showing multiplication
- Let me try: maybe it's showing 1×1=1, 1×2=2, 1×3=3?
- So the next would be 1×4=4?
- Or the blank after 3 should be 4?

Actually, re-reading more carefully: "1, x, 2, 1×, 3, ___"
I think this is showing a sequence where:
- 1st term: 1
- 2nd term: x (unknown/blank)
- 3rd term: 2
- 4th term: 1× (which might indicate multiplication)
- 5th term: 3
- 6th term: ?

If the pattern is counting: 1, _, 2, _, 3, _
Then the missing terms fill in: 1, 1, 2, 2, 3, 3?

Or if it's showing multiplication facts: 1×1=1, 1×2=2, 1×3=3, so next is 1×4=4

Given the context and "1×" shown, I believe the answer is 4 (continuing the pattern 1, 2, 3, 4...)

Let me reconsider: The sequence appears to be 1, [blank], 2, [1× shown], 3, [blank]
If we're filling in blanks in order: 1, 1, 2, 2, 3, 3 doesn't seem right.

More likely: This is showing the pattern 1, 2, 3 with the next being 4.
The "x" and "1×" might just be annotations.

Final interpretation: The sequence is 1, 2, 3, and the next number is 4.
