Daily 5 Math Practice: 3 Nov Worked Solutions

When a child gets a question wrong, the answer alone rarely says why. Was it a slip in the subtraction, a misread unit, or a step that was skipped? Seeing the full working is often what turns a wrong answer into a useful one. This post gathers the five questions from each grade's Daily 5 video in this set, with the hints, steps and answers written out inside closed folds. Your child can try each question independently, then open the working and find the exact line where their own method went a different way. That comparison is often worth more than the mark itself.

Pick your child's grade and watch its video, then pause it before starting the questions. Work each one on paper with the fold shut. Afterwards, open the solution and check it line by line. If the answers differ, look for the first step where the two pieces of working part ways.

Primary 3 (P3) Math: Whole Numbers, Area and Perimeter, Fractions

This P3 set mixes four-digit addition, the area of a rectangle, a missing numerator in a pair of equivalent fractions, and two harder word problems. One follows an art club's membership across several terms; the other compares amounts of water using the idea of times as much. In the longer stories, list each change in order before calculating, and check whether the question wants an amount or a difference.

Question 5 · Volume — multiplicative comparison · hard

A kettle contains

900

ml of water. It contains

6

times as much water as a cup. A bottle contains

500

ml of water. How much more water does the bottle contain than the cup? Give your answer in ml.

Primary 5 (P5) Math: Fractions, Geometry, Whole Numbers

This P5 set covers writing a mixed number as a decimal, the area of a parallelogram, order of operations with brackets, converting metres to centimetres, and a harder ratio problem about savings that ends with a fraction step. In the order-of-operations question, ask your child which part comes first. In the ratio problem, read to the end before starting, since the final question is about what remains.

Question 5 · Ratio Word Problems · hard

The ratio of Marcus's, Ling's and Dev's savings is

3 : 2 : 6

. Marcus and Ling together save

$20

less than Dev. Ling then spends

\frac{1}{4}

of their savings. How much does Ling have left?

Show the worked solution

Hint 1

Compare Dev's ratio units with Marcus and Ling together; the difference in units matches the stated savings difference.

Hint 2

Their difference is

6 - (3 + 2) = 1

unit. One unit is

20 \div 1 = 20

→ 20.

Final step

Reuse that unit value for Ling:

2 \times 20 = 40

savings. The unspent three quarters are

\frac{3}{4} \times 40 = 30

→ 30

Primary 6 (P6) Math: Data Analysis, Decimals, Measurement

The P6 questions draw on data and measurement: an increase read from a line graph, a division rounded to one decimal place, a time comparison between two people in a race, a pie chart given in percentages, and the height of water poured into a tank. Read each value off the graph against its scale. In the race question, decide who took longer before doing any subtracting.

Question 1 · Line Graphs · easy

The line graph shows the number of televisions sold each month from January to May. What was the increase in the number of televisions sold from February to March?

Number of Televisions Sold Each Month

Show the worked solution

Hint 1

Read the value for February off the graph

→ $280$ .

Hint 2

Read the value for March off the graph

420 - 280

→ 140

Answer: 140

Question 2 · Fraction-Decimal Conversion and Rounding · easy

Find the value of

9 \div 14

. Round your answer to 1 decimal place.

Show the worked solution

Hint 1

To round to 1 decimal place, divide 9 by 14 as far as the second decimal place.

Hint 2

Look at the second decimal digit: five or more means round up, and less than five means keep the first decimal digit.

Final step

Divide:

9 \div 14 \approx 0.64

. Its second decimal digit is less than five, so keep the first decimal digit

→ 0.6

Answer: 0.6

Question 3 · Time Word Problems (Comparison) · easy

Benson took 195 min to complete a race. He was 30 min slower than Carson. How long did Carson take to complete the race? Give your answer in min.

Show the worked solution

Hint 1

Benson was slower than Carson, so Carson took less time. Take 30 min away from Benson's time.

Hint 2

Split 30 min into 10 min and the rest:

30 - 10 = 20

. Take 10 min away from Benson's time:

195 - 10 = 185

→ 185 min.

Final step

Take away the other 20 min:

185 - 20 = 165

. So Carson took

195 - 30 = 165

min

→ 165

Answer: 165
