Patterns, bar graphs and dot plots
Answers are for parents and teachers.
1
Make your own pattern. Start at 5 and use the rule add 20. Write the first six numbers.
5, 25, 45, 65, 85, 105.
2
Ask 8 people at home or at school which fruit they like best: orange, banana or guava. Make a tally and then a bar graph with a title and labels on both axes.
Any correct survey. The three totals add up to 8, the bars match the tally, and the graph has a title and labelled axes.
3
Ask 10 people how many brothers and sisters they have. Make a dot plot with a title, a labelled number line and a key.
Any correct plot. It has exactly 10 dots, the key says each dot is 1 person, and the stack for the most common number is the tallest.
4
Count the dots. How many plants are in this plot, and which number of tomatoes is the most common?
9 plants, because 1 + 2 + 3 + 2 + 1 = 9. The most common number is 5 tomatoes.
5
A pattern starts 3, 6, 9, 12. What is the 8th number? Count by 3s.
24: 3, 6, 9, 12, 15, 18, 21, 24.
