Manic Monday - Part-Part-Whole Flip Cards

It's been a while since I've created anything for my math class, but after spending two days at the NCTM regional conference in Richmond, I was inspired to make some new resources. Today I'm sharing two sets of flip cards for working on subitizing, part-part-whole, missing addend problems, and basic facts.

Each set contains 55 cards covering addition facts from 0+0 through 9+9. You can access all 100 facts by using the Commutative property and covering a different part of the flip card. Here's what the packet and cards look like.

Once you print these back-to-back and cut along the dotted lines, you can select which part of the card you wish to "hide." Here's what a finished card looks like.

These flip card sets can be used to meet the following Common Core Standards for Math.

• K.OA.5.  Fluently add and subtract within 5.
• 1.OA.3.  Apply properties of operations as strategies to add and subtract. Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)
• 1.OA.4.  Understand subtraction as an unknown-addend problem. For example, subtract 10 – 8 by finding the number that makes 10 when added to 8.
• 1.OA.5.  Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).
• 1.OA.6. Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
• 2.OA.2.  Fluently add and subtract within 20 using mental strategies. By end of Grade 2, know from memory all sums of two one-digit numbers.

Monday Math Freebie - Arctic Animal Races

Towards the end of the semester my students and I spent some time on probability and data analysis. I made a set of spinner activities to look at the notion of fair and unfair. They were pretty boring and focused on color, so I decided to dress them up and create a lesson and resources using Arctic animals.

In this set of activities, students:

• experiment with fair and unfair spinners
• tally and record the results of their spins
• graph the results of their experiments 
• determine what makes a spinner fair or unfair

Probability does not appear in the Common Core standards until middle school. However, students can still use probability activities to collect and analyze data. With this in mind, these activities can be used to meet the following Common Core Standards for Math.

• 1.MD.C.4 Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.
• 2.MD.D.10 Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Solve simple put-together, take-apart, and compare problems1 using information presented in a bar graph.
• 3.MD.B.3 Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Solve one- and two-step “how many more” and “how many less” problems using information presented in scaled bar graphs. For example, draw a bar graph in which each square in the bar graph might represent 5 pets.

Here's what the packet and resources look like.

Monday Math Freebie - Geometry Vocabulary Puzzle

I've been playing around with Formulator Tarsia, "a tool for creating activities in a form of jigsaws or dominos for later use in a class." Sadly, this free software only works on a PC, so I used Wineskin to convert the program to an app that would run on a Mac. It's a bit glitchy (at times), but now I have VMware Fusion, a program that allows you to run Windows on a Mac. I don't use it often, but it's been great for playing around with Tarsia.

This is a very long introduction to say that I am working on a series of puzzles for math. The first is a triangle shaped puzzle to review geometry vocabulary. Simply laminate and cut the large triangles apart. Students try to assemble the 16 pieces into a large triangle. Students should notice that the three corner pieces have writing on only 1 edge. The side pieces have writing along 2 edges, while the interior pieces have writing along all three edges.

Here's what the pieces and completed puzzle look like.

Monday Math Freebie - Fall-Themed Addition Games

I created two new addition games this weekend by putting a twist on some old favorites for practicing multiplication. Those games, and a few others with a fall theme can be found in this addition packet.

Here's what the games look like.

Monday Math Freebie - Be a Number Detective

I've been working on number sense riddles for some time now. Today I'm sharing my first set for the numbers 1-32. Each card has 3 or 4 clues and ends with the question "What number am I?" In general, these cards are designed to help develop number sense and thinking flexibly about numbers and how they are used and represented in our world. Terms such as multiple, factor, even, odd, prime and composite are used.

If you want to use these in a math center, I have included a poster. Here's what the cards and poster look like.

Monday Math Freebie - Dots and Boxes Games

While searching for resources for teaching scientific notation I came across a middle school version of the dot game where students were required to simplify exponents and record numbers in scientific notation. I loved this idea and wrote to the author asking if I could adapt his idea for the elementary classroom. My thanks to Kevin Koch for giving me permission to create these resources!

In this version of the dot game, students draw line segments and form boxes as usual. When they complete a box, they earn one point. However, if they complete a box with a number sentence, they must say the number sentence aloud and give the solution. Answering correctly earns a player extra points. Once all the boxes have been made, players total their scores. The player with the highest score is the winner.

The two versions I have today are for practicing basic facts, one in addition and one in multiplication. Here's what they look like.

Monday Freebie - Nature of Science Bookmarks

In SCIENCE FOR ALL AMERICANS, F. James Rutherford and Andrew Ahlgren explore what constitutes scientific literacy.  They describe the scientifically literate person as one who "knows that science, mathematics, and technology are interdependent enterprises with strengths and limitations; who understands key concepts and principles of science; who recognizes both the diversity and unity of the natural world; and who uses scientific knowledge and scientific ways of thinking for personal and social purposes."

Chapter 1: The Nature of Science, focuses on the scientific world view, scientific methods of inquiry, and the nature of the scientific enterprise and their importance to developing scientific literacy. I also recommend reading Understanding Science 101, an in-depth, multi-part course that explains what science is, how it works, and how it is intertwined with our lives and with society more broadly.

The ideas presented in these sources and others have been condensed and listed on these bookmarks.

Monday Math Freebie - Math Talk Cards

Making sense of problems, reasoning through problem solving strategies, and communicating and explaining answers are important skills students must develop. These skills can be found in the NCTM Process Standards, the Strands of Mathematical Proficiency specified in the National Research Council’s report Adding It Up, and in the Standards for Mathematical Practice found in the Common Core Standards.

To encourage students to talk about math, this packet contains a set of 24 question cards and 24 sentence starter cards. Simply cut the cards apart and put on a ring. They can be used by the teacher to guide whole-class or small group discussion, or by students working in small groups at centers or stations.

Here's what the cards look like.

Monday Freebie - Bill of Rights Resources

For the last four years my methods class in science and social studies has been team taught with an amazing social studies specialist from a local school division. This semester the class has returned solely to me, and I'll admit to being a bit nervous about it. So, I've been spending a lot of time brushing up on content and pedagogy for elementary social studies.

Since Constitution Day is just a few short weeks away, today I'm sharing a packet of resources on the Bill of Rights. In this packet you'll find a series of notebook pages for students to illustrate each amendment and write about them in their own words. You will also find a cut and paste activity where students sort rights and protections into the categories of individual freedoms, rights of the accused, and protection from government. Finally, you'll find a few suggestions for web sites and children's book that may be helpful.

Here's what the pages look like.

Monday Math Freebie - Numbers to 20

As I prepare for the start of the semester, I find myself working on materials for teaching number sense and place value.

In this packet you'll find three sets of numbers sense puzzles to 20. Each set contains the number in graphic as well as standard and word form. One set uses ten frames, one tally marks, and one base-ten blocks.

Here's what the puzzles look like.
