Math Is Marvelous
We are currently working on Unit 1 in our Everyday Math 4 program.
Summary Statement: The study of multiplication strategies and the measurement of time and mass through the use of appropriate tools, and modeling with mathematics.
Focus Standards for this Unit
Operations & Algebraic Thinking
Represent and solve problems involving multiplication and division.
3.OA.1 Interpret products of whole numbers, e.g., interpret 5 × 7 as the total number of objects in 5 groups of 7 objects each. For example, describe a context in which a total number of objects can be expressed as 5 × 7.
3.OA.3 Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.
Multiply and divide within 100.
3.OA.7 Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of Grade 3, know from memory all products of two one-digit numbers.
Number & Operations in Base Ten
Use place value understanding and properties of operations to perform multi-digit arithmetic.
3.NBT.1 Use place value understanding to round whole number to the nearest 10 or 100.
3.NBT.2 Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction
Measurement & Data
Solve problems involving measurement and estimation.
3.MD.1 Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a number line diagram.
Key Vocabulary: Array, bar graph, column, data, division, division symbol, estimate, fact family, factor, gram, kilogram, mass, multiplication, multiplication symbol, number grid, open number line, precise, product, round, row, zero
Supporting Vocabulary: close-but-easier numbers, elapsed time, equal groups, equal sharing, pan balance, Quick Looks, strategy, weight
Standards of Mathematical Practice for Unit 1
Model with mathematics. Mathematically proficient students can apply the mathematics they know to solve problems arising in everyday life, society, and the workplace.
Use appropriate tools strategically. Mathematically proficient students consider the available tools when solving a mathematical problem. These tools might include pencil and paper, concrete models, a ruler, a protractor, or a calculator.
