Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol...
Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.
Apply properties of operations as strategies to add and subtract.2 Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 ...
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - ...
Determine the unknown whole number in an addition or subtraction equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = _ - 3, 6 + 6 = _.
Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it wi...
Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.
Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes.
Use objects and pictorial models to solve
word problems involving joining, separating, and comparing sets within 20
and unknowns as any one of the terms in the problem such as 2 + 4 = [ ]; 3 + [ ] = 7; and 5 = [ ] - 3;
Determine the unknown whole number in an
addition or subtraction equation when the unknown may be any one of the three
or four terms in the equation; and
Identify two-dimensional shapes, including circles, triangles, rectangles,
and squares, as special rectangles, rhombuses, and hexagons and describe their
attributes using formal geometric language;
Identify three-dimensional
solids, including spheres, cones, cylinders, rectangular prisms (including cubes),
and triangular prisms, and describe their attributes using formal geometric
language;
Illustrate that
the length of an object is the number of same-size units of length that, when
laid end-to-end with no gaps or overlaps, reach from one end of the object to
the other;
A PowerPoint providing a series of warm-up activities for Grade 1 students across the mathematics curriculum.
This teaching resource is an interactive PowerPoint that provides a series of math warm-up activities that cover areas across the curriculum. You can do these quick activities to help warm-up for a particular focus lesson, or use them to break up the day to keep students fresh for learning. Some activities supply instructions for interactive games, while others are interactive templates that can be displayed on your classroom whiteboard with a projector.
