*Because these are leveled, the lower level cards can be used to teach 2.NBT.1.
Print cards using short-edge binding and cut them apart to make a stack. Students work in small groups. The student whose turn it is selects a card and everyone in the group solves on a piece of paper, in their journal, or on a dry erase board.
They reveal answers to the group; and turn over the card to see the answer and a model solve. If any student misses a problem, the one who answered correctly and moved their piece teaches the student who solved incorrectly how they arrived at the correct answer.
You can choose to let students “steal a turn”, so that if the student whose turn it is misses the problem, the next student who solved correctly gets the point. This keeps them on their toes!
I've used this method with great success because students hold each other accountable and it allows you to give valuable feedback to students and “be everywhere all at once”.
The cards can be used with almost any game imaginable – tallies, Candy Land, Jenga, Connect Four, etc.
Since this product is designed to scaffold towards 4.NBT.1, most of the cards have “doubles” so students can begin to discuss this concept (ex- 153,301).
In the first lesson, I used base-ten block manipulatives to help students understand a digit is ten times as many as the digit to the left and asked them to discuss this concept when they saw a card with a “double”.
In the second lesson, I had students prove the doubles on all of the cards they had discussed during the first lesson using equations (ex- 900,000 ÷ 90,000 = 10).
There is a Place Value House included in this pack. I recommend printing it and putting it in a page protector to use during this lesson. This organizer is great because it helps when teaching subtraction with ungrouping, I always tell students they don’t have any sugar and they have to go knocking next door to get 10 more. Students can use the second row of boxes to write expanded or word form. For word form, students can use their hand to cover the right side to say the thousands number and then the left side to say the ones side.
Also included is a song I wrote to help students with Place Value.
