• “¿Puedes usar tus marcadores/fichas para contarme lo que ocurrió en la historia?” // “Can you use your markers/counters to tell me what happened in the story?”
• “Había 4 marcadores en la escuela. ¿Cuáles marcadores/fichas muestran los 4 marcadores que estaban en la escuela? ¿Cuáles marcadores/fichas muestran los 3 marcadores que Elena trajo a la escuela?” // “There were 4 markers at school. Which markers/counters show the 4 markers that were at school? Which markers/counters show the 3 more markers that Elena brought to school?”

• Invite a student who used markers to share.
• “¿Cómo muestran los marcadores lo que ocurrió en la historia?” // “How do the markers show what happened in the story?”
• Invite a student who used counters or connecting cubes to share.
• “¿Cómo muestran las fichas lo que ocurrió en la historia?” // “How do the counters show what happened in the story?” (Those counters show the markers that were at school. Those counters show the markers that Elena brought to school.)
• “Había 4 marcadores y Elena trajo 3 marcadores más. 4 marcadores y 3 marcadores es 7 marcadores. Podemos escribir eso como ‘4 y 3’ o ‘’” // “There were 4 markers and Elena brought 3 more markers. 4 markers and 3 markers is 7 markers. We can write that as ‘4 and 3’ or ‘’.”

The purpose of this activity is for students to interpret how a drawing represents a story problem (MP2). Students solve a Take From, Result Unknown story problem. Because balls are the objects in the story problem, it may be easier to relate the circles in a picture to the balls in the story. Students are introduced to the number 0 in the Activity Synthesis. They learn how to form the number and practice tracing it in their books. 

• Draw 5 circles in a line with 5 of them crossed out.

  

• “Lin hizo este dibujo. ¿Cómo muestra este dibujo lo que ocurrió en la historia?” // “Lin drew this picture. How does this picture show what happened in the story?”
• If needed, ask “¿En qué parte del dibujo ven los 5 balones que están en el patio de recreo?” // “Where do you see 5 balls that are on the playground in the picture?” and “¿Por qué 5 de los círculos están tachados?” // “Why are 5 of the circles crossed out?”
• “¿Cuántos balones hay en el patio de recreo ahora?” // “How many balls are on the playground now?” (None, zero.)
• “Había 5 balones en el patio de recreo. Diego llevó 5 balones para adentro. Podemos escribir eso como 'tengo 5 y quito 5' o ''. Ahora hay cero balones en el patio de recreo. Tengo 5 y quito 5, quedan 0” // “There were 5 balls on the playground and Diego brought 5 of the balls inside. We can write that as ‘5 take away 5’ or ‘’. There are zero balls on the playground now. 5 take away 5 is 0.”
• Demonstrate writing “0.”
• “Este es el número 0. Comienzo en la parte superior, dibujo una línea y la cierro” // “This is the number 0. I start at the top and draw a line all the way around.”
• ”Usen su dedo para dibujar el 0 en el aire. Ahora usen su dedo para dibujar el número 0 sobre su pupitre” // “Use your finger to draw 0 in the air. Now use your finger to draw the number 0 on your desk."
• “Usen su dedo para trazar el número 0 en su libro. Ahora tracen el número 0 con su lápiz” // “Use your finger to trace the number 0 in your book. Now trace the number 0 with your pencil.”

The purpose of this activity is for students to learn Stage 3 of the Math Fingers center. Students each hold up some fingers on one hand and work with their partner to figure out how many fingers they are holding up together. Students color the fingers on the recording sheet and write a number to show how many fingers there are altogether. The recording sheet can be laminated or placed in a sheet protector so it can be used multiple times by students.

• “Cuando descifraban con su compañero cuántos dedos tenían ambos levantados, ¿hubo algún momento en el que no tuvieron que contar los dedos? ¿Cómo supieron cuántos dedos había?” // “Was there a time when you didn’t need to count the fingers to figure out how many fingers you and your partner held up together? How did you know how many fingers there were?” (I could see that I had 2 fingers and my partner had 2 fingers. I know that 2 and 2 is 4. I only had 1 finger up and my partner had 3 fingers up. I know that 3 and 1 more is 4.)
