Decomposing Number Exploration
Students will decompose a number up to 20 using manipulatives and graphic organizers.
Planting the Seeds of Perimeter
Students will create planters that meet specific perimeter dimensions. The students will need to determine the number of sides and the perimeter for their planter.
Balancing Act
Students use a pan balance model and manipulatives to identify a total that balances two parts. The use of the pan balance will help to develop the concept of equality. Students will develop the language of equality by reading and identifying the following expressions; balances, is the same as, is equal to, and equal before the symbol for equality is introduced. Students will identify an unknown part in a balance situation. Students will communicate ideas, explain, and justify how they solved problems.
The Shapes Around Us
Students will make connections between real-world objects and the attributes of two-dimensional shapes.
Centers in Subtraction
Students will participate in multiple centers including a guided math center that reinforces subtraction concepts.
Comparing in Stations
Students will extend their knowledge of greater than and less than to numbers 80–120. Students will work in stations to deepen their understanding and have multiple experiences with the concept.
It’s All About the Bend, No Breaking
Students will experiment with choosing tools to measure around a previously created pet habitat in preparation for choosing appropriately sized food bowls. Students will use a graphic organizer to record tools chosen and to explain why those tools were or were not a good choice for continuous measurement.
Subtraction Seekers
Students will be introduced to subtraction in an inquiry-based lesson that uses concrete examples and allows students to explore through different settings and scenarios.
