Cluster - Measure and estimate lengths in standard units.
[2.MD.A.4] - Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit.
[2.MD.A.3] -
Estimate lengths using units of inches, feet, centimeters, and meters.
[2.MD.B.5] -
Use addition and subtraction within 100 to solve word problems involving lengths that are given in the same units, e.g., by using drawings (such as drawings of rulers) and equations with a symbol for the unknown number to represent the problem.
[2.ESS.2.1] -
Investigate and compare the effectiveness of multiple solutions designed to slow or prevent wind or water from changing the shape of the land.*
Clarification Statements: Solutions to be compared could include different designs of dikes and windbreaks to hold back wind and water, and different designs for using shrubs, grass, and trees to hold back the land; Solutions can be generated or provided.
[2.ESS.2.2] -
Map the shapes and types of landforms and bodies of water in an area.
Clarification Statements: Examples of types of landforms can include hills, valleys, river banks, and dunes; Examples of water bodies can include streams, ponds, bays, and rivers; Quantitative scaling in models or contour mapping is not expected.
[2.LS.4.1] -
