Help! The numbers in our equations have run away and left their answers alone! In this lesson, students will review their math facts and knowledge to solve Ken Ken like puzzles and bring the numbers back to their places.
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.
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.
Introduce place value to your emerging mathematicians while focusing on the numbers 11–20. In this lesson, students will practice separating teen numbers into 10 ones and some additional ones using unifix cubes and ten frames.
