![]() You can laminate the alligators and put adhesive magnets on the back to use on your chalkboard or dry erase board.Īfter a teacher’s request, I’ve added a set of smaller alligators that you can use for small groups. ![]() If your child is a little older and is ready for it, use the alligators to compare: The following diagram shows how to use the greater than, less than and equal symbols. And this is how to put the greater than equal symbol, which you are looking for within your text. Select the symbol you want to add, and then click Insert. Scroll down or up until you find it on the symbol library. This was quite challenging for her, so after a few more problems I let her get back to her reading. Now it’s time to look for the greater than equal sign, the less than or equal to sign. Then I made it even tougher with the above example. With an accompanying illustration, she was able to see that those are equal. When I saw that she knew that “2,465 is greater than 2,456”, I created more challenging problems involving fractions. I started with some larger numbers to give her practice with place value. These simple on the floor activities were far too easy for my Seven, who is going into second grade. After figuring out the answer, I had him read it using the words on the alligator. I got out my color tiles from my teaching days. We used a few toys with my Five too, but it became obvious that to help him work with larger numbers we’d need small manipulatives. I would set out small piles and ask my Four to tell me which was larger without counting. He understood that when the piles had equal amounts, he needed to choose the equal sign. If your child has trouble, you could draw a simple number line and show him how the larger numbers are farther on the line. My Four had no trouble figuring out greater than/less than for amounts under 10. After doing a variety of counting activities over the last year, he can count objects up to about 20 without much difficulty. They are used in inequalities, which are math statements that are used to show that. After counting each pile, he identified the larger one and chose which alligator he would need to swallow up the bigger amount. The arrow symbols are the less than symbol and the greater than symbol. We started by getting out our toy food and putting it in small piles that I knew my Four could count. After printing on cardstock and laminating, I brought them to the playroom. Perform Addition and Subtraction in the order they appear.You can do this activity using only two things:Ī) the free alligator printables (get them at the end of this post)ī) something to count, like a stack of toys or small math manipulatives (for older kids, you just need a dry erase or chalk board)Īmong the three kids (ages 4, 5, and 7) we learned more about:įirst, I created some simple alligator less than, greater than, and equal to printables.Perform Multiplication and Division in the order they appear.Solve within Parentheses and Brackets from the inside out.The rules are: summarized in the table below. Consider the following example:Īt first this may look daunting, but it is really quite simple. When you are given a mathematical expression or an equation, the order in which mathematical operations are performed is very important. The symbol ≈ means approximately equal to.The symbol ≥ means greater than or equal to.The symbol ≤ means less than or equal to. ![]() (Read as "doesn't equal" or "is not equal to." Less than () ![]() Division can also be indicated by placing one quantity (the numerator) over another quantity (the denominator) as shown below.Ĥ4/123 = 0.3577 Equals (=) & Doesn't Equal (≠).There are three commonly used ways to indicate division. Or simply a number next to a parenthetic expression, e.g., 5(6+2) = 40 The symbol looks like an alligators mouth open in front of the bigger number or quantity.The use of the asterisk to indicate multiplication is commonly used in spreadsheets (e.g., Excel) and in algerbraic expressions. Note that this symbol is generally avoided in algebraic equations because of the common use of "x" to indicate an unknown quantity. There are three commonly used means of indicating multiplication ![]()
