• planning a camping or hiking trip; planning for quantities and materials needed per individual and group over time

one-step equations with an unknown number, using all operations
• one-step equations for all operations involving an unknown number (e.g., ___ + 4 = 15, 15 – □ = 11)
• start unknown (e.g., n + 15 = 20; 20 – 15 = □)
• change unknown (e.g., 12 + n = 20)

• telling time in five-minute intervals
• telling time to the nearest minute
• First Peoples use of numbers in time and seasons, represented by seasonal cycles and moon cycles (e.g., how position of sun, moon, and stars is used to determine times for traditional activities, navigation)

regular and irregular polygons
• describing and sorting regular and irregular polygons based on multiple attributes
• investigating polygons (polygons are closed shapes with similar attributes)
• Yup’ik border patterns

perimeter of regular and irregular shapes
• using geoboards and grids to create, represent, measure, and calculate perimeter

line symmetry
• using concrete materials such as pattern blocks to create designs that have a mirror image within them
• First Peoples art, borders, birchbark biting, canoe building
• Visit a structure designed by First Peoples in the local community and have the students examine the symmetry, balance, and patterns within the structure, then replicate simple models of the architecture focusing on the patterns they noted in the original.

one-to-one correspondence and many-to-one correspondence, using bar graphs and pictographs
• many-to-one correspondence: one symbol represents a group or value (e.g., on a bar graph, one square may represent five cookies)
