Dive deep into word problems with this lesson that teaches students to sketch base-ten blocks to add multiples of 10 and two-digit numbers. Use alone or with the lesson plan **Let's Build It! Two-Digit Addition.**
Let’s start building numbers! Just as building skyscrapers is a visual representation of mathematics, students will use the visual representation of base-ten blocks to add—or build—onto a two-digit number.
Who doesn’t like to spend money and plan parties? Students will subtract two-digit numbers as they calculate the remaining money for their party supplies. They will subtract in multiples of ten and focus on place value.
