22. Alice has 12 markers. Ben has half as many markers as Alice. M is the number of markers that Ben has. Which equation can Ben use to find the number of markers that he has? • 12 ÷ 2 = M • 12 + 2 = M • 12 × 2 = M • 12 – 2 = M B 400

23. A. 12 ÷ 2 = M B 400

24. Anthony’s family plants 15 trees each weekend. Construct a table showing the total number of trees Anthony’s family planted after 1, 2, 3, 4, and 5 weekends. Describe the pattern that tells the number of trees that the family has planted. If t is the total number of trees planted and w is the number of weeks, write an expression for the total number of trees, t, that are planted after w weeks. If the pattern continues, how many trees will have been planted after 9 weeks? ________ Show or explain how you found your answer. B 500

25. Students need to construct a table that shows weeks in one column and the total number of trees planted in the other column. To find the total number of trees that are planted each week, students can multiply the week number by 15 (the number of trees planted each week), or add 15 to the number of trees planted in the previous week. For example, for week 1, the total number of trees planted is (1 x 15 = t). For week 2, the number of trees planted is (2 x 15 = 30). To write this rule as a number sentence, students need to substitute w for ‘week’ and t for “total number of trees” . To find the total number of trees, t, after the 9th week, students need to substitute 9 for w in the expression, (9 x 15 = 135). Students could also continue the pattern in their table by adding 15 each week until they get to 9 weeks. B 500

26. A theater has 14 rows of seats. Each row has the same number of seats.  The theater has a total of 168 seats. Which equation can be used to find the number of seats, s, in each row? • 168 × 14 = s • 14 × s = 168 • 168 – s = 14 • 14 + s = 168 C 100

27. B. 14 × s = 168 C 100

28. The graph shows Beth’s earnings while baby-sitting. Which statement describes how Beth’s total earnings change as the number of hours of baby-sitting increases? • For every hour, the amount she earns doubles. • For every five hours, the amount she earns increases by $1.     • For every five hours, the amount she earns increases by $10. • For every hour, the amount she earns increases by $5. C 200

29. D. For every hour, the amount she earns increases by $5. C 200

34. The table shows the number of cans of paint Joe used to paint benches. How many benches can he paint with 8 cans of paint? ___ Use pictures, words or numbers to explain how you found the number of benches. C 500

35. The number of benches is twice (two times) the number of cans: 22 = 4, 42 = 8, 62 = 12. So, when there are 8 cans, there are 16 benches. 16 benches. The pattern is that you multiply the number of cans by 2 to get the number of benches you can paint. 8 × 2 = 16 16 benches. The table shows that the number of benches goes up by 4 so I added 12 + 4 = 16. 16 benches. The number of cans is doubled to get the number of benches. 8 + 8 = 16. The focus of this task is to provide evidence of analyzing, extending and describing patterns. The response correctly identifies the number of benches and provides adequate support to explain how to find the answer. C 500
