1 s Master 1.22 Name Date Extra Practice 1 Lesson 1: Exploring Increasing Patterns 1. Use Pattern Blocks. Make the next 2 figures in each increasing pattern. a) 2. Write the pattern rule for each pattern in question 1. Lesson 2: Creating Increasing Patterns 1. Start with 4 squares. Add 3 squares each time. Draw the first 3 figures of this pattern on grid paper. 2. Figure 3 is missing in this increasing pattern. Sketch what it should be. Explain how you know.

2 Master 1.23 Extra Practice 2 Lesson 3: Comparing Increasing Patterns 1. Look at this pattern. a) Write the pattern rule. Make a different pattern that uses the same pattern rule. 2. Here is an increasing pattern. Draw a pattern that uses: a) the same starting point but grows by a different amount a different starting point but grows by the same amount

3 Master 1.24 Extra Practice 3 Lesson 4: Increasing Number Patterns 1. Fill in the missing numbers. Write the pattern rule. a) 17, 27, 37,,,, 48, 50,,,, 58, 2. Write the first 6 numbers in each pattern. a) Start at 28. Add 10 each time. Start at 35. Add 5 each time. 3. Use numbers and words to describe this pattern. Lesson 6: Exploring Decreasing Patterns 1. Draw the next 2 figures in each decreasing pattern. a) 2. Write the pattern rule for each pattern in question 1.

4 Master 1.25 Extra Practice 4 Lesson 7: Creating and Comparing Decreasing Patterns 1. Here are 2 patterns. Pattern A Pattern B a) Tell the pattern rule for each pattern. How are the patterns the same? How are they different? Lesson 8: Decreasing Number Patterns 1. Copy each pattern. Write the pattern rule. Fill in the missing numbers. a) 85, 75, 65,,,, 78, 76,,,, 68, 2. Write the first 5 numbers in each pattern. a) Start at 66. Count back by 3s each time. Start at 75. Count back by 5s each time. 3. Use numbers and words to describe this pattern.

5 Master 1.26 Extra Practice Sample Answers Extra Practice 1 Master a) Lesson 1 1. a) 2. a) Start with Figure 1. Add 2 square and 2 triangle Pattern Blocks each time. Start with 1 square Pattern Block. Add a new row of blocks each time. Each row should have 1 more block than the row above it. Lesson Start with Figure 1. Add 2 squares each time, one at each end. Extra Practice 2 Master 1.23 Extra Practice 3 Master 1.24 Lesson 4 1. a) 47, 57, 67, 77 Start at 17. Add 10 each time. 52, 54, 56, 60 Start at 48. Add 2 each time. 2. a) 28, 38, 48, 58, 68, 78 35, 40, 45, 50, 55, , 63, 65, 67, 69, 71, 73, 75, 77, 79; Start at 61. Add 2 each time until you get to 79. Every second square in the pattern is shaded on the hundred chart. Lesson 6 1. a) Lesson 3 1. a) Start with Figure 1. Add 2 white squares each time, one at each end.

6 2. a) Start with Figure 1. Remove 1 column of 3 circles each time. Start with Figure 1. Remove 1 X from each side each time. Extra Practice 4 Master 1.25 Lesson 7 1. a) Start with Figure 1. Remove 1 X each time. Start with Figure 1. Remove 1 row of 3 Xs each time. Both patterns are shrinking patterns. The first figure in each pattern is the starting point. The other figures in the pattern decrease by the same amount each time. The patterns look different because each pattern has a different starting point and each pattern shrinks by a different amount. Lesson 8 1. a) 55, 45, 35, 25; Start at 85. Count back by 10s each time. 74, 72, 70, 68, 66; Start at 78. Count back by 2s each time. 2. a) 66, 63, 60, 57, 54 75, 70, 65, 60, , 77, 75, 73, 71, 69, 67, 65, 63, 61; Start at 79. Count back by 2s each time until you get to 61. Every second square in the pattern is shaded on the hundred chart.
