Relation to 4th grade standards
Instead of focusing on the relationships between multiplication and division, the fourth grade teacher could use the standards below and focus on the relationships found only in mulitplication. The teacher could teach fact family relationships and have students discuss the meaning of relationships. Students could use manipulatives, graph paper, and pictures to show their work. Students will also begin using the same strategies with single and double digit numbers.
Use the four operations with whole numbers to solve problems.
CCSS Math Concept 4.OA.A.1
Interpret a multiplication equation as a comparison, e.g., interpret 35= 5x7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal statements of multiplicative comparisons as multiplication equations.
CCSS Math Content 4.OA.A.2
Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison 1
CCSS Math Concept 4.OA.A.3
Solve multi-step words problems posed with whole numbers and having whole number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unknown quantity. Assess the resonableness of answers using mental computation and estimation strategies including rounding .

Relation to 6th grade standards
Students in the 6th grade can use the same basic project of this unit. Students would not necesarrily need to go into the math portion of the unit but the building of the house on an ecosystem would be beneficial to learning about structures and processes of plants. The teacher can allow students to elaborate on abiotic and biotic factors of the ecosystem in their models.
6.L.1 Understand the structures, processes and behaviors of plants that enable them
to survive and reproduce.
6.L.1.1 Summarize the basic structures and functions of flowering plants required for survival, reproduction and defense.
6.L.1.2 Explain the significance of the processes of photosynthesis, respiration, and transpiration to the survival of green plants and other organisms.
6.L.2 Understand the flow of energy through ecosystems and the responses of populations to the biotic and abiotic factors in their environment
6.L.2.3 Summarize how the abiotic factors (such as temperature, water, sunlight, and soil quality) of biomes (freshwater, marine, forest, grasslands, desert, Tundra) affect the ability of organisms to grow, survive and/or create their own food through photosynthesis.
