Understanding Basic Math Concepts

Mr. Montgomery's lesson focuses on understanding place value in two-digit numbers and forming addition sentences using blocks. The lesson introduces touch math and number lines as tools for solving addition problems. It emphasizes the commutative property of addition, showing that the order of numbers doesn't affect the sum. Students engage in practice problems and a coloring activity to visualize addition. The lesson concludes with instructions for independent practice.
