Texas Go Math Grade 1 Lesson 10.7 Answer Key 10 More, 10 Less

Essential Question
How can you identify numbers that are 10 more or 10 less than a number?
Answer:
10 more or 10 less gives strategies for mentally finding less than a two-digit number without having to count. This strategy is done by adding or subtracting a one from the ten’s place.
For example:
To find 10 more than 25, you add 1 to the 2 to get 35.
To find 10 less than 25, you subtract 1 from the 2 to get 15.
This method is key for developing mental maths skills.

For The Teacher

• Read the following problem. Tony has 2 boxes of markers and 2 more markers. Pat has 10 fewer markers than Tony. Jan has 10 more markers than Tony. How many markers does each child have?
  Answer: Tony has 12 markers.
  Pat has 2 markers.
  Jan has 22 markers.
  Explanation:
  The number of markers tony has=10+2=12.
  The number of markers Pat have=12-10=2 (because pat is having 10 less than tony so I subtracted )
  The number of markers Jan is having=12+10=22 (because Jan is having 10 more than tony so I added).

Texas Go Math Grade 1 Lesson 14.1 Answer Key Classify and Sort Two-Dimensional Shapes

Explore

Draw to sort the shapes. Write the sorting rule.

Answer: Sorting rules:
We can sort two-dimensional shapes into groups.
A sorting rule is a rule that tells us how to sort objects.
Read the sorting rule. Circle the shapes that follow the rule.

FOR THE TEACHER • Read the following aloud. Devon wants to sort these shapes to show a group of triangles and a group of rectangles. Draw and write to show how Devon sorts the shapes.
Answer: Here the question was asked that we need to sort a group of triangles and rectangles. We will represent by diagrammatically.
First, we can sort two-dimensional shapes by comparing:
1. How many sides do they have.
2. How many vertices(corners) do they have.
3. If they have curves or not.
4. The length of their sides.

Is there a shaper that did not go in your groups? Explain.
Answer: No
Explanation:
No, there are no shapes that did not go in your group, because here we are dealing with two-dimensional shapes and we have triangle, square, circle, rectangle and so on. from the above questions so all of them are grouped. Here are some ways to sort two-dimensional shapes.

Read the sorting rule. Circle the shapes that follow the rule.

Question 1.
more than 3 sides

Answer: Rectangle, square.
Explanation:
Here, the question was asking more than 3 sides. So it was a rectangle and square that are having 4 sides.

Question 2.
circles

Answer:

Problem Solving

Draw 2 different two-dimensional shapes that follow both parts of the sorting rule.

Question 3.
4 sides are the same length
Answer: Square
Explanation:

Square: All sides are equal.

• All four interior angles are equal to 90°
• All four sides of the square are congruent or equal to each other
• The opposite sides of the square are parallel to each other
• The diagonals of the square bisect each other at 90°
• The two diagonals of the square are equal to each other

 

Question 4.
Multi-Step Write sorting rules to show two different ways to sort some of these shapes.

Answer: Triangle and rectangle.
Explanation:

Rectangle sorting rules:

The fundamental properties of rectangles are:

• A rectangle is a quadrilateral
• The opposite sides are parallel and equal to each other
• Each interior angle is equal to 90 degrees
• The sum of all the interior angles is equal to 360 degrees
• The diagonals bisect each other
• Both the diagonals have the same length

Triangle sorting rules:

• The sum of all the angles of a triangle (of all types) is equal to 180°.
• The sum of the length of the two sides of a triangle is greater than the length of the third side.
• In the same way, the difference between the two sides of a triangle is less than the length of the third side.
• The side opposite the greater angle is the longest side of all the three sides of a triangle.
