I have always remembered from elementary school, AND taught to my elementary students that when comparing numbers, the alligator always eats the bigger piece (number). The visual that comes to mind and even the shape of the “greater than” symbol just screams alligator mouth!
If you are covering number and operations in base-10, then this packet is just right for your students. It has so many skills using a variety of numbers and number forms.
If you laminate the cards after cutting them out, and the center signs, all you will need to do year after year is make enough copies of the recording sheets for your students to use. This packet is perfect for first and second graders. It could also be used with 3rd graders who need extra practice
with these skills.
-36 two-digit number cards
-36 two-digit number word cards
-36 two-digit expanded form number cards
**All of the two-digit (small) number cards have a yellow dot to help you more easily gather materials for centers
-36 three-digit number cards
-36 three-digit number word cards
-36 three-digit expanded form number cards
**All of the three-digit (small) number cards have a
blue dot to help you more easily gather materials for centers
-36 large two-digit number cards
-36 large base-10 block cards
**All of these 2-digit cards have a pink dot to help you more easily gather materials for centers
-36 large three-digit number cards
-36 large base-10 block cards
**All of these 3-digit cards have a green dot to help you more easily gather materials for centers
RECORDING SHEETS (to differentiate instruction & vary activities)
-Which One is Greater, Gator?
-comparing, greater than, less than, or equal to
-easily differentiated for two-digit or three-digit numbers
-students can compare
-numbers to numbers
-numbers to number words
-base-10 block numbers
-Give or Take a Gator
-adding and subtracting numbers
-students can add
-number + number
-number words + number words
- 2 numbers or 3 numbers
-students can subtract two numbers or 2 number words
-Block that Gator!
-identifying numbers based on base-10 block pictures
- identify numbers based on base-10 block pictures, draw the base-10 blocks, and write the number it represents
-find a matching card for each base-10 block card, draw the base-10 blocks, and write the number it represents (just an extra step in finding the matching number card)
-More or Less, Gator!
-identifying numbers that are 10 more or 10 less (use 2- digit number cards)
-identifying numbers that are 100 more or 100 less (use 3- digit number cards)
-Place a Gator!
-identifying place value in 2-digit and 3-digit numbers
-students can write numbers from a number card and identify ones, tens, and hundreds (3-digit numbers) place
-students can also use the expanded form cards and write the 2-digit number or 3-digit number that the expanded form represents
-students will write the number on the card
-students can then round up the 2-digit number to the nearest 10, or
-students can round up the 3-digit number to the nearest 100
This pack is CHOCK FULL of options & activities to use for working with numbers and operations in base ten! It is a packet for comparing numbers – either in numeral form, number words, expanded form, or with base-ten blocks.
SMALL NUMBER CARDS – there are 36 of each card (numerals, number words, and expanded form)
1. Numeral to numeral comparison (ex. 48 > 23)
2. Numeral to number word comparison
(ex. 76 < eighty-five)
3. Numeral to expanded form comparison
(ex. 59 = fifty + 9)
Obviously, students would have to be familiar with all 3 of these ways of writing numbers to be able to interchange these with them. Only include the cards in the center if your students have been exposed to the form.
There are 36 of each type of small cards in 2-digits and 36 of each type in 3-digits. The 2-digit cards are geared more toward 1st graders while the 3-digit cards are geared more toward 2nd graders, but feel free to use them to differentiate for your students at whatever level they are working.
There are 36 larger cards in numeral form and in base-10 block form. The base-10 blocks took up a lot more room and were just too tiny to put on the smaller cards. Students can still use the large cards with the smaller cards though. The numbers on the large cards are different from the numbers on the smaller cards
to give you and your students a little more options and further practice.
