Introduction
This unit bundles student expectations that address representing and solving one- and two- step addition, subtraction, multiplication, and division problems, including problems using categorical data represented with a frequency table, dot plot, pictograph, or bar graph. According to the Texas Education Agency, mathematical process standards including application, a problem-solving model, tools and techniques, communication, representations, relationships, and justifications should be integrated (when applicable) with content knowledge and skills so that students are prepared to use mathematics in everyday life, society, and the workplace.
Prior to this Unit
In Unit 09, students gained fluency, efficiency, and accuracy while solving one- and two-step problems involving addition and subtraction with sums and minuends within 1,000 and multiplication and division with products and dividends within 100. In Unit 04, students summarized data sets with multiple categories using a frequency table, dot plot, pictograph, or bar graph with scaled intervals.
During this Unit
Students revisit and solidify essential understandings of operational understandings. Students apply their understanding of place value, properties of operations (associative, commutative, and distributive properties of multiplication), and whole number operational relationships (addition, subtraction, multiplication, and division) to solve one- and two-step, real-world problem situations that include interpreting categorical data from a graph (frequency tables, dot plots, pictographs, and bar graphs). Students demonstrate their understanding of solution strategies by selecting appropriate tools, models (pictorial models, number lines, arrays, area models, equal group models), and equations to represent problems and solutions. Students analyze a variety of solutions in order to justify and evaluate the reasonableness of a solution.
Unit Vocabulary:
- Addend – a number being added or joined together with another number(s)
- Bar graph – a graphical representation to organize data that uses solid bars that do not touch each other and a scaled axis to show the frequency (number of times) that each category occurs
- Categorical data – data that represents the attributes of a group of people, events, or objects
- Counting (natural) numbers – the set of positive numbers that begins at one and increases by increments of one each time {1, 2, 3, ..., n}
- Data – information that is collected about people, events, or objects
- Difference – the remaining amount after the subtrahend has been subtracted from the minuend
- Dividend – the number that is being divided
- Divisor – the number the dividend is being divided by
- Dot plot – a graphical representation to organize small sets of data that uses dots (or Xs) and an axis to show the frequency (number of times) that each category occurs
- Equation – a mathematical statement composed of equivalent expressions separated by an equal sign
- Expression – a mathematical phrase, with no equal sign or comparison symbol, that may contain a number(s), an unknown(s), and/or an operator(s)
- Factor – a number multiplied by another number to find a product
- Fluency – efficient application of procedures with accuracy
- Frequency table – a table to organize data that lists categories and the frequency (number of times) that each category occurs
- Graph – a visual representation of the relationships between data collected
- Minuend – a number from which another number will be subtracted
- Pictograph – a graphical representation to organize data that uses a picture or symbol, where each picture or symbol may represent one or more than one unit of data, to show the frequency (number of times) that each category occurs
- Product – the total when two or more factors are multiplied
- Quotient – the size or measure of each group or the number of groups when the dividend is divided by the divisor
- Subtrahend – a number to be subtracted from a minuend
- Sum – the total when two or more addends are joined
- Whole numbers – the set of counting (natural) numbers and zero {0, 1, 2, 3, ..., n}
Science: Investigating Ecosystems
During this Unit
Students demonstrate safe and healthy practices as outlined in the Texas Education Agency-approved safety standards while engaging in descriptive investigations. They observe and describe the physical characteristics of environments and how they support populations and communities of plants and animals within an ecosystem. Students also describe environmental changes such as floods and droughts where some organisms thrive and others perish or move to new locations. Moreover, students identify and describe the flow of energy in a food chain and predict how changes in a food chain affect the ecosystem such as removal of frogs from a pond or bees from a field. Additionally, students communicate and discuss their observations and record data in their notebooks. Furthermore, students consider environmentally appropriate and responsible practices with resources during investigations.
Key Content Vocabulary:
- Community – populations that live in the same place at the same time
- Consumer – an organism that eats other organisms (plants and / or animals) for food
- Decomposer – an organism that gets energy by feeding on dead materials and waste
- Ecosystem – the living and nonliving components of an environment
- Food chain – representation of the flow of energy from the Sun through producers to consumers and decomposers in an ecosystem
- Perish – to die
- Population – all of the organisms of the same species that live in the same place at the same time
- Predator – an animal that naturally preys on others
- Prey – an animal that is hunted and killed by another for food
- Producer – an organism that makes its own food (e.g., plants)
- Thrive – to live, grow, and reproduce successfully
