Part A: Multiple Choice
Circle the best answer for each question.
1. Sam has 3 red marbles and 4 blue marbles. How many in all?
A) 5
B) 6
C) 7
D) 8
3 red marbles plus 4 blue marbles equals 7 marbles because 3 + 4 = 7. You can count on from 3: say 4, 5, 6, 7.
2. Which group shows exactly 9 objects?
A) 7 and 1 stars
B) 4 and 4 dots
C) 5 and 4 circles
D) 6 and 2 squares
5 circles and 4 circles make 9 because 5 + 4 = 9. The other groups add up to different numbers.
3. Maya counted 10 fish. Then 3 swam away. How many left?
A) 5
B) 6
C) 7
D) 8
Maya started with 10 fish and 3 swam away, so she has 7 left because 10 minus 3 equals 7.
4. Which shows a way to make 8?
A) 3 + 3
B) 4 + 4
C) 5 + 4
D) 2 + 5
4 + 4 equals 8 because two equal groups of 4 combine to make 8.
Part B: Fill in the Blank
Write the correct answer on each line.
1. 6 eggs in a basket and 2 on the table. That is 8 eggs total.
6 eggs in the basket plus 2 on the table makes 8 eggs because 6 + 2 = 8.
2. Count backward from 10 to 7: 10, 9, 8, 7
When counting backward, each number goes down by 1, so after 8 comes 7.
3. You have 5 crayons and give away 2. You have 3 left.
5 crayons minus 2 given away leaves 3 crayons because 5 - 2 = 3.
4. A tally of IIII I stands for the number 6.
IIII is 5 tally marks and the extra I makes 6. A group of 5 plus 1 more equals 6.
5. What is 1 more than 9? 10
1 more than 9 is 10 because 9 + 1 = 10. The number 10 comes right after 9 when you count.
