We’re looking forward to seeing you at Expo night! 4th graders are sharing their creative Mission Layout design, demonstrating the formula for perimeter and area. Learners are using the vocabulary length and width to name dimensions of a rectangle. We will begin to learn about angles, rays, and line segments as well. Learners will explore making angles using rubber bands and geoboards for a hands on experience. This is a part of our Geometry and Measurement unit.

4th grade is enjoying designing their creative Mission layout. They will determine perimeter and area for each structure within the Mission. Learners have the opportunity to add 2 structures of their choice after they include 7 required structures. Once finished, these projects will continue to be worked on in Science class, as learners construct circuits to light up their Mission. The week will end with a literature based activity around the book Spaghetti and Meatballs for All by Marilyn Burns. Learners will be faced with the task of seating guests for a dinner party with limited tables and chair configurations. To complete the task, learners will need to determine the perimeter and area of each configuration.
4th grade will apply their skills practiced last week with perimeter and area, to designing their own California Mission during our 3 days together this week. They will take the time the plan each structure within the mission, drawing the layout, and calculating the perimeter and area. The next step in the planning phase will be piecing each building and feature of the mission in an overall design. The final draft will be a full mission, drawn to scale, with labeled measurements. This project supports their study of California history in Humanities and is an opportunity for creativity for each learner. The rubric can be found on the website under “Useful Information -> Grading -> Math.”
4th Graders will complete their unit on Patterns and Functions this week. Having had many opportunities to investigate and develop their understanding of patterns, Learners will be challenged through a variety of culminating, pattern-oriented tasks that involve geometric shapes, numeric sequences, and input/output tables (or charts). This provides an appropriate transition to their interdisciplinary Mission Projects as well as our next Math Unit on Geometry. Also, please continue to regularly check with (and quiz) your child on their math facts involving all four operations, especially multiplication. While Learners should have mastered their X-tables up through the 12s by January of their 3rd grade, you may be surprised that some are still struggling with these fundamentals, which causes additional challenges to their math development in general. Thank you for your continued support!
Happy 2016! Aloha and welcome back! 4th grade begins the new year with more pattern and function investigations. Learners will study growing shape patterns this week. Spatial relationships may come easily for some children. However, if identifying sequential patterns are a challenge for your child, you can help at home by acknowledging patterns observed in real life, like in advertisements or clothing designs. We will also have time to do some basic skill review. Hopefully Learners did not forget skills over the break, but we will recall these skills just in case to begin the year with a solid foundation.
