Primary ABQ Early Numeracy

Engaging young learners in foundational math concepts can be effectively achieved through play-based activities. Utilizing playdough in sensory manipulative centers helps children grasp the part-whole relationship and develop early subtraction strategies.

Primary ABQ Early Numeracy

Primary ABQ Early Numeracy Building early math strategies and key concepts through play based centers.

ONE to ONE counting

This early numeracy skill of One-to-One counting shows students can point at/tag each object only once.
This center is marshmellows in a container. Students have to count out the same number of marshmellows as the number shown. Pompoms can be used or even smaller marshmellows.

Counting Sequence

Next step: Students can begin subtraction concepts by eating a goldfish from the bowl!
The early counting sequence is being able to name all the numbers in the correct order. 1,2,3 and so on.
This center engages children with goldfish crackers on a bowl placemat. They role the die and put the corresponding number of goldfish onto the bowl.

Coordinating

Early Counting involves coordinating the counting word with the tagging of each object. Saying one and pointing to one button.
Integration with Literacy helps children make connections to authentic problem solving. Pete the Cat is a well loved series and engages children in counting the buttons.
In this center students role the dice. They determine the number on the dice and put the same number of groovy buttons on the shirt.

Manipulatives in Math

Having concrete objects such as manipulatives in this stage decreases the amount of information that needs to be held in the student’s head (Fosnot 2015). This demonstrates why manipulatives are so crucial in developing big ideas in Math. Students will later be able to count more efficiently and use tracking.

Conservation

The early concept of conservation is that children understand the set of things are the same no matter their organization. In this instance the dots can be arranged in a variety of ways and students begin to understand it still represents 8 dots.
Number Representation. Symbol and the word are written for literacy integration. This activity is connects students with an authentic experience of cooking in the kitchen.
In this center Students are making and cooking cookies in the kitchen. They are using a flipper to turn over the cookies to determine which set of chocolate chips matches which number.

Cardinality

Early Cardinality is understanding that the final object tagged and counted represents all of the objects in the bag as a set.
This center are several bags that contain objects. Students can move the objects around in the bags to count them. Each bag is labelled with a letter. Students record the amount of objects in each bag on the sheet.

Strategies for early Addition and Subtraction

5 students can wear these tags. When the monkey falls off the bed the teacher writes the subtraction equation on the smart board.
This activity integrates music and kinesthetic multiple intelligence.
Subtopic
This center can be done in a large group setting.

Lawson's Continuum

The continuum demonstrates early numeracy development in young children.
This continuum will help teachers to see early numeracy phases, strategies and key concepts. It is useful to know where learners are at and how to guide them to the next strategies on the continuum.
This game practices the concepts of subitizing
This game can be played as a whole class. Each child chooses a bingo card. The teacher announces the number. The children can find any representation of that number and cover it on their card.

Main topic

The use of playdough provides sensory manipulative discovery and play in the development of numeracy concept of part whole relationship.
This center encourages early subtraction strategies.

Subitizing

This early strategies helps students to see sets of numbers and allows them to have more efficient computation and mental math in later years.
Students can practice subitizing number patterns from 1-10 using dice, 5-frames, 10-frames, or paper plates with bingo dot dabbers.
Subitizing is a fundamental numeracy concept. It is the ability of know the number of object based on their arrangement without having to count each one.
Encourage the children to squish the balls as they count.
Students practice early numeracy by rolling playdough into the number symbols. They also make balls to squish into the 10 frames to represent each number.
