Year 3 Math Guided Journey

Math Journal

This year, children will create a math journal. Each week, parents will have their children write in their math journals to demonstrate what they have learned. The journal will be a three-ring notebook with three sections as follows:

• Math Knowledge--what the child has learned or would like to learn in his or her own words
• Explanations--a demonstration of what the child has learned--diagrams, step-by-step solutions to a sample problem, etc.
• Reference--this should be a section the child can refer to for formulas, weights and measurements, metric units of measure, problem-solving tools, properties of math, etc.

Lesson Plans

Key Concepts and Systems to Keep in Mind

Numbers: We can use whole numbers to count and identify sets of concrete items. We can also use them for identifying ordinal position and comparing sets of varying sizes (more than, less than, equal to). Written whole-number digits can represent quantities. By adding two or more whole numbers together, we can make a larger number, and by subtracting, we can make a smaller number. We can divide or separate whole numbers into smaller parts called fractions and fractional parts can be expressed as decimals.      

     
Geometry: There are plane and solid shapes. Some basic shapes are circles, squares, rectangles, triangles, cones, spheres, and cubes. There are also special shapes, such as hexagons and trapezoids. We can draw shapes and identify them in the environment. Shapes can have faces, vertices, and angles.   

     
Measurement: We can measure objects using standard (length, weight, etc.) and non-standard (foot length, hand span, etc.) units of measurement. We use clocks and calendars to measure time and thermometers to measure temperature. We can measure using customary and metric units.  

         
Patterns: We can classify and sort objects by physical attributes, such as size, shape, and color. We can count by developing a number pattern--skip counting. We can identify and develop repeating patterns. We can create and identify patterns using objects, shapes, and numbers.         

   
Probability and Statistics: We can decide whether an event is likely or unlikely using probability and chance. We can organize and collect data by counting and using tally marks. We can identify, display, and analyze information using charts, tables, and graphs.

            
Money: Coins--pennies, nickels, dimes and quarters--can be identified by physical attributes. We can count money, and we can even skip count with it.
