Unit 2:
Developing Operational Procedures

TEKS
5.3A Use addition and subtraction to solve problems involving whole numbers and decimals.

5.4 Use strategies including rounding and compatible numbers to estimate solutions to addition, subtraction,
multiplication, and division problems.

5.10C Select and use appropriate units and formulas to measure length, perimeter, area, and volume.

Process TEKS:
5.15A Explain and record observations using objects, words, pictures, numbers, and technology.

5.15B Relate informal language to mathematical language and symbols.

5.16A Make generalizations from patterns or sets of examples and non-examples.

Related TEKS:
5.2D Use models to relate decimals to fractions that name tenths, hundredths, and thousandths.
Unit 2:
1. How can you use addition and subtraction to solve problems involving whole numbers and decimals?

2. What units of measure are used to measure length?

3. What operations can be used to find the perimeter of a figure?
Objective:
I will add and subtract whole numbers and decimals to solve word problems.

TEKS:
5.3C Use division to solve problems involving whole numbers (no more than two-digit divisors and three-digit
dividends without technology) including interpreting the remainder within a given context.
