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.

Do your students ever want to just hurry and finish their homework? Your students can use the number line jumping strategy to quickly add two-digit numbers and show their understanding of place value and expanded form in the process.

Guide students to use base ten blocks to solve two-digit by one-digit addition problems with regrouping. This lesson can be used independently or paired with the lesson Adding it All Up.
