Taught inMake a ten to add Subtract back to ten Ways to make 10 Facts that go togetherand 8 more
1.NR.2.5
Use the meaning of the equal sign to determine whether equations involving addition and subtraction are true or false.
Taught inNot every equation is true What the equal sign means True or false?The total can come first
1.NR.2.6
Determine the unknown whole number in an addition or subtraction equation relating to three whole numbers.
Taught inThe missing number anywhere A missing start Check by putting it back Both sides must match
1.NR.2.7
Apply properties of operations as strategies to solve addition and subtraction problem situations within 20.
Taught inAny order, same total Find the ten first Facts that go together Three numbers in a story
1.PAR.3.1
Investigate, create, and make predictions about repeating patterns with a core of up to 3 elements resulting from repeating an operation, as a series of shapes, or a number string.
Taught inGrowing patterns Patterns from a rule Position is not value Find the part that repeats

Geometry

1.GSR.4.2
Compose two-dimensional shapes (rectangles, squares, triangles, half-circles, and quarter-circles) and three-dimensional figures (cubes, rectangular prisms, cones, and cylinders) to create a shape formed of two or more common shapes and compose new shapes from the composite shape.
