These are the Essentual Learnings/Grade Level Expectation Categories for this week:

  • 1.2.1 Analyze how a change in a linear dimension affects other linear measurements (perimeter, circumference) and area measurements. W
  • 1.2.5 Apply formulas to find measurements of circles, triangles, and rectangular prisms. W
  • 1.3.2 Apply understanding of the characteristics of rectangular prisms and circles. W
  • 1.2.6 Understand and apply strategies to obtain reasonable estimates of circle measurements, right triangles, and surface area for rectangular prisms. W
  • 3.1.1 Analyze information from a variety of sources to interpret and compare information. W
  • 5.1.2 Apply different mathematical models and representations to the same situation. W
  • 5.3.1 Understand that mathematics is used in daily life and extensively outside the classroom.

Fraction - Decimal Review
Spatial Reasoning Exercises
Group Problems

OBJECTIVE: •To understand and use line symmetry (mirror symmetry) •To look at a cube building and see the orthogonal views without being distracted by depth perception •To discover that the base outline and the front and right views can be used to represent a cube building •To draw sets of plans for cube buildings •To match buildings to sets of building plans ACTIVITIES/ASSESSMENT: Students will work with MIRA and blocks as an introduction to spatial manipulatives, volume and surface area, orthographic and isometric projections. A secondary activity will be a set of group problems to be handled on a case by case basis. NOTES: Familiarization activities. HOMEWORK: Will be evaluated daily.

Fraction - Decimal Review
Spatial Reasoning Exercises
Group Problems

OBJECTIVE: •To develop efficient strategies for reading a set of building plans and for constructing a building that matches a given set of plans •To reason visually and analytically about cube buildings •To make observations about similarities and differences in the buildings that fit a given set of plans or incomplete set of plans ACTIVITIES/ASSESSMENT: Working from a building plan. Students will construct the 10 models from the building plan using an orientation sheet. Students will then sketch the top, front and side views on graph paper. Secondary activity will either be group problesm or fraction decimal review. NOTES: using cubes HOMEWORK: Will be evaluated daily.

Fraction - Decimal Review
Spatial Reasoning Exercises
Group Problems

OBJECTIVE: •To become proficient at reading a set of plans and constructing a building that matches a set of plans •To reason visually and analytically about cube buildings •To understand that several minimal buildings may fit a set of plans, but only one maximal building •To develop a recording scheme •To keep track of all buildings that fit a set of plans ACTIVITIES/ASSESSMENT: After completing and verifying the orthographic projections, students will strart to work on isometric sketches using dot-grid paper. Each of the 10 plans will have 2 isometic sketchs, a front-left and a front-right. Secondary activities will include group problems and fraction decimal exercises. NOTES: HOMEWORK: Will be evaluated daily.

Fraction - Decimal Review
Spatial Reasoning Exercises
Group Problems

OBJECTIVE: •To understand how the dots are arranged on isometric dot paper and how this arrangement allows cube buildings to be drawn from corners •To visualize the relationship between the angles of an actual cube and an isometric drawing of a cube •To copy existing figures onto isometric dot paper •To construct buildings that fit isometric drawings and make isometric drawings of cube buildings •To use 2-0 isometric models of cubes as design tools •To develop strategies for reading an isometric drawing and constructing a building that matches the drawing •To observe similarities and differences in buildings produced to fit isometric drawings ACTIVITIES/ASSESSMENT: Complete the isometic drawings. Start on creating nets for simple shapes and then leading to more complex objects such as the described buildings. Story problems and fractions. NOTES: HOMEWORK: Will be evaluated daily.
