Ben saw 8 turtles on the sand. 6 of them went back home. How many turtles are still on the sand?
2 turtles
10 = 11
False
Is the number of objects even or odd?
3
Let's make a fact family using these numbers:
1, 5, 6
How are these numbers related through addition and subtraction?
1 + 5 = 6
5 + 1 = 6
6 - 1 = 5
6 - 5 = 1
Let's create a graph. First, we'll take a survey or a class vote. Here's the question:
What is your favorite color?
***Teacher and class can record the results and create a graph together using chart paper.
Zoe has a collection of 6 toy horses. Her aunt gave her some more for her birthday. Now she has 9 toy horses. How many did her aunt give her?
3 horses
7 = 4 + 3
True
Is the number of objects even or odd?
6
Even
Let's make a fact family using these numbers:
4, 3, 7
How are these numbers related through addition and subtraction?
4 + 3 = 7
3 + 4 = 7
7 - 4 = 3
7 - 3 = 4
Let's create a graph. Next, we'll have to create our graph. We need a title and categories. What should they be?
**Teacher and class can create a graph together whole group. After taking the survey, have students create a title and label the categories.
Julian had 12 toy dinosaurs. He gave some to his cousin and now he only has 5 left. How many dinosuars did Julian give his cousin?
7 dinosaurs
1 + 4 = 5 + 0
True
Is the number of objects even or odd?
10
Even
Are these equations part of the same fact family?
3 + 1 = 4
1 + 3 = 4
4 - 3 = 1
4 - 1 = 3
Yes
Let's create a graph. After that, we'll need to create a key and scale. Let's say each "x" or crayon is worth 1 vote. What numbers should we use?
**Teacher and class will create a class picture graph together on chart paper. For this part, create the key and scale numbered 0 - 10 (or whatever is best for your class). Decide on what symbol will represent each person's vote.
Abbi has 8 toy cars and Ethan has 11. How many more toy cars does Ethan have than Abbi?
Ethan has 3 more than Abbi.
6 + 2 = 2 + 6
True
Ava said 6 is even because when she makes two groups, there are 3 in each group with none left over.
Is she correct?
Yes.
Which equation does not belong with the others because it is not part of the fact family?
a. 4 + 2 = 6
b. 4 + 6 = 10
c. 6 - 4 = 2
d. 6 - 2 = 4
b does not belong with the others.
Let's create a graph. Finally, let's add the data (the information we collected from our survey).
Let's also talk about what we notice.
**Teacher and class will complete the class favorite color graph and discuss what they notice.
Ayden drew some pictures. He gave 3 to his son and 7 to his brother. How many pictures did he have at first?
10 pictures
5
Explain to your partner how you know if a number is even or odd.
***Answers will vary
-Lay out or draw the number of objects and make pairs. If there are none left over, the number is even.-Draw two circles/groups. Give one object to each group until they run out. If they have the same number of objects in each group, the total number is even.
Rowen said he does not know the answer to the problem 11 - 9 =
How can he use addition to help him?
a. 11 + 9 =
b. 9 + __ = 11
b. 9 + 2 = 11
He can think about the related addition facts from the fact family.
11 (total) - 9 (part) = ? (part)
9 (part) + 2 (part) = 11 (total)
Let's answer questions about our graph. Here are some examples:
How many students voted?
Which color received the most votes?
How many more votes did ___ receive than ____?
Questions and answers will vary.
